Description

[Technical Field]

[0001] The present invention relates to indenonaphthopyrane compounds having a perfluoroalkyl-substituted aryl group or a perfluoroalkyl-substituted heteroaryl group bonded at the 11th position by a sulfide bond, as well as photochromic compositions and photochromic articles containing such compounds. [Background technology]

[0002] In response to specific wavelengths of electromagnetic radiation (or "chemical rays"), photochromic compounds such as indenonaphthopyran (or indenocondensed naphthopyran) typically undergo transformation from one form or state to another, each form having its own characteristic or distinguishable absorption spectrum. Typically, when exposed to chemical rays, many photochromic compounds transform from a ring-closed form corresponding to the inactive (or decolorized, e.g., substantially colorless) state of the photochromic compound to an open-ring form corresponding to the activated (or colored) state of the photochromic compound. In the absence of exposure to chemical rays, such photochromic compounds reversibly transform back from the activated (or colored) state to the inactive (or decolorized) state. Compositions containing or coated with photochromic compounds (e.g., in the form of photochromic coating compositions) and articles such as eyeglass lenses typically exhibit colorless (e.g., transparent) and colored states corresponding to the colorless and colored states of the photochromic compound contained therein or coated thereon.

[0003] Photochromic indenonaphthopyrane compounds are generally desirable to provide a significant level of dark color when exposed to chemical radiation. It is also generally desirable that photochromic indenonaphthopyrane compounds rapidly decolorize to an inactive (or decolorized) state when not exposed to chemical radiation. Indenonaphthopyrane compounds that provide a combination of a significant or high level of dark color when exposed to chemical radiation and a rapid decolorization rate when not exposed typically and undesirably have an overly dark decolorized state (or color) and / or insufficient fatigue resistance. [Overview of the project] [Problems that the invention aims to solve]

[0004] It would be desirable to develop novel indenonaphthopyran compounds that provide a combination of a marked or high level of darkening upon exposure to chemical radiation and a rapid fading rate in the absence of chemical radiation exposure, without excessively dark decolorization (or bleaching) and / or poor fatigue resistance. [Means for solving the problem]

Furthermore, with respect to equation (I), R4 and R 5 is each independently selected from substituted or unsubstituted alkyl, or R 4 and R 5 together form a substituted or unsubstituted spiro ring. Further, with respect to formula (I), R 6 is independently for each n, and R 7 is independently for each m, and in each case independently, is selected from amino, a substituted or unsubstituted nitrogen-containing heterocyclic ring, a halo group, a substituted or unsubstituted alkyl, a substituted or unsubstituted alkoxy, a perfluoroalkyl, or a substituted or unsubstituted alkylthio.

[0108] Part 1 of the following examples describes the synthetic preparation of comparative indenonaphthopyran compounds (Comparative Examples / Compounds CE1, CE2, CE12, and CE13) and indenonaphthopyran compounds according to the present invention (Examples / Compounds 3-11, 14, and 15). Part 2 provides an overview of the comparison in Part 1 and the evaluation of the indenonaphthopyran compounds of the present invention.

[0109] Part 1 Explanation of synthesis The following Scheme-1 outlines the synthesis of the indenonaphthopyran compound, particularly Comparative Example 1 (CE1). Scheme-1 also includes other comparative compounds in the following examples, as well as the starting materials and / or intermediates and / or alternative species used to synthesize the compounds of the present invention.

[0110] Scheme-1 Compound (CE1) of Comparative Example 1 [ka] Comparison compound CE1: Comparative compound CE1 was prepared according to the following procedure.

[0111] Step 1: 9-Bromo-2,3-dimethoxy-7,7-dipropyl-7H-benzo[c]fluoren-5-ol (20 g) (100), imidazole (4.48 g), 4-(dimethylamino)pyridine (0.54 g), and anhydrous N,N-dimethylformamide (60 mL) were placed together in a round-bottom flask and stirred. The mixture was cooled to -5 to 0°C by immersing the flask in saturated saline solution and an ice bath. Then, tert-butyldimethylsilyl chloride (7.94 g) (TBDMSCl) was added to the reaction mixture in four equal parts at 5-minute intervals. The reaction mixture was allowed to return to room temperature naturally, and then stirred for 16 hours. After that, it was poured into ice water and extracted twice with ethyl acetate. The combined organic layer was washed twice with saturated saline solution, dried over sodium sulfate, and concentrated to dryness. The resulting residue was filtered through a silica gel short plug, and the filter was washed with a mixture of 25% ethyl acetate and 75% hexane. By concentrating the mother liquor to dryness, an intermediate product (103') and an amber-colored oil (25.02 g) corresponding to (103) in Scheme-1 were obtained. [ka]

[0112] Step 2: In a two-necked round-bottom flask, hexane (55 mL) and morpholine (3.87 g) (106) were mixed. The flask was immersed in an ice bath, and then 15.4 mL of a 2.5 M n-butyllithium (n-BuLi) solution in hexane was added dropwise from a syringe over 5 minutes. Next, the intermediate product (103) (11.00 g) from step 1 was added to the mixture, followed by the addition of anhydrous tetrahydrofuran (70 mL). The reaction mixture was warmed to room temperature over 1 hour, and then poured into ice water. This was washed twice with ethyl acetate, and then the combined organic layers were washed with saturated brine, dried over sodium sulfate, and concentrated to dryness. The resulting residue was filtered through a silica gel short plug, and the filter was washed with a mixture of 25% ethyl acetate and 75% hexane. The mother liquor was concentrated to dryness to obtain the following intermediate products (9.23 g), (109'), and an amber-colored oil corresponding to (109) in Scheme-1. [ka]

[0113] Step 3: The intermediate product from Step 2 (4.62 g) (10⁹'), isooctyl 3-mercaptopropionate (1.78 g), N,N-diisopropylethylamine (1.91 g), and toluene (28 mL) were placed together in a round-bottom flask and stirred. The mixture was purged with nitrogen gas for 20 minutes. Tris(dibenzylideneacetone)dipalladium (0) (0.20 g) and 4,5-bis(diphenylphosphin)-9,9-dimethylxanthene (0.26 g) were added to the mixture. This was heated at 110°C for 90 minutes, and then cooled to room temperature. Anhydrous N,N-dimethylformamide (26 mL), followed by a 40% sodium tert-pentoxide solution in toluene (8.13 g), was added to the reaction mixture and stirred for 10 minutes. Next, 1-bromo-4-fluorobenzene (5.17 g) was added, and the mixture was then heated at 120°C for 1 hour. After cooling to room temperature, the reaction mixture was poured into ice water, and then dilute hydrochloric acid solution was added until the pH reached 5. This was then extracted twice with ethyl acetate. The combined organic layers were washed twice with saturated brine, dried over sodium sulfate, and then concentrated to dryness. The resulting residue was purified using silica gel flash chromatography and eluted with a mixture of 25% ethyl acetate and 75% hexane. The fractions containing the desired intermediate product were combined and concentrated to dryness. The resulting solid was slurryed in a mixture of 10% ethyl acetate and 90% hexane, and then recovered by vacuum filtration to obtain the intermediate product (1.50 g) (112) represented by the following structural formula. [ka]

[0114] Step 4: The intermediate product (112) (1.00 g) from Step 3, 1,1-bis(4-methoxyphenyl)prop-2-in-1-ol (0.63 g) (115), 4-pyridinium p-toluenesulfonate (0.06 g) (PTSA), and 1,2-dichloroethane (20 mL) were placed together in a round-bottom flask and heated at 83°C for 2 hours. After cooling to room temperature, the reaction mixture was filtered through a silica gel short plug, and the filter was washed with a mixture of 25% ethyl acetate and 75% hexane. The mother liquor was concentrated to dryness. The resulting residue was purified using silica gel flash chromatography and eluted with a mixture of 25% ethyl acetate and 75% hexane. The fractions containing the target product were combined and concentrated to dryness. Methanol was added to the resulting residue to precipitate the solid, which was then recovered by vacuum filtration. NMR analysis of the solid was consistent with the following representative structure (0.97 g) (118). [ka]

[0121] Part 2 Evaluation of indenonaphthopyrane compounds in Part 1 Each indenonaphthopyran compound from Part-1 was incorporated into a polyurethane coating system in the same molar percentage as described in Examples 1-3 of U.S. Specification 8,608,988B2, and applied to 2-inch x 2-inch (5.1cm x 5.1cm) test chips made of CR-39® monomer (PPG Industries, Inc.) with the same coating thickness. All coated test chips were cured at 125°C for 1 hour.

[0122] Each coated test chip was first conditioned by irradiating it with 365 nanometer ultraviolet light at a distance of approximately 14 centimeters for 10 minutes to activate the photochromic material in the coating. The UVA (315-380 nm) irradiance at the chip was measured using a LICOR® Model Li-1800 spectroradiometer and found to be 22.2 watts per square meter. Subsequently, each test chip was placed under a 500 watt high-intensity halogen lamp at a distance of approximately 36 centimeters for approximately 10 minutes to decolorize (inactivate) the photochromic material. The irradiance at the chip was measured using a LICOR® spectroradiometer and found to be 21.9 Klux. After that, the coated test chips were placed in a dark environment at room temperature (i.e., 70-75°F, i.e., 21-24°C) for at least 1 hour before being tested / measured on an optical bench. Prior to optical bench measurement, the coated test chips were measured for ultraviolet absorbance at 390 nanometers.

[0123] The percentage transmittance (%T) of each coated test chip was determined using CIE Y values ​​according to the CIE 15:2004 colorimetric method using a D65 light source and a 10° observer. The a* and b* values ​​used herein refer to a* and b* values ​​measured using UltraScan Pro (Hunter Labs) according to the CIE 15:2004 spatial colorimetric method using a D65 light source and a 10° observer.

[0124] The BMP optical bench was fitted with two 150-watt ORIEL® Model #66057 xenon arc lamps positioned perpendicular to each other. The optical path from lamp 1 was directed to pass through a 3mm SCHOTT® KG-2 bandpass filter and appropriate ND filters to contribute to the required UV and partially visible irradiance levels. The optical path from lamp 2 was directed to pass through a 3mm SCHOTT® KG-2 bandpass filter, a SCHOTT® shortwave 400nm cutoff filter, and appropriate ND filters to provide supplemental visible irradiance. A 2-inch x 2-inch (5.1cm x 5.1cm) 50% polka dot beam splitter set at 45° to each lamp was used to mix the two beams. Irradiance intensity was adjusted using a combination of ND filters and voltage control of the xenon arc lamps. Dedicated software (i.e., BMPSoft version 2.1e) was used with the BMP to control timing, irradiance, air cell and sample temperatures, shutter, filter selection, and response measurements. A ZEISS® spectrophotometer, model MCS501, with a fiber optic cable for transmitting light through the coated test chips, was used for response and color measurements. Photopic response measurements were collected for each coated test chip. The output of the optical bench, i.e., the amount of light to which the coated test chips were exposed, was 6.7 watts / m² (W / m²) integrated at 315–380 nm. 2The irradiance was adjusted to 50 Klux, integrated over UVA and 380–780 nm. The setpoint measurement of this output was performed using an irradiance probe and a calibrated Zeiss spectrophotometer. A quartz window and a self-centering sample holder were mounted on the sample cell of the coated test chip. The temperature inside the sample cell was controlled to 23°C by software with a modified Facis model FX-10 environment simulator. Measurements of the dynamic photochromic response and color of the coated test chip were performed using the same Zeiss spectrophotometer with a fiber optic cable for transmitting light from a tungsten halogen lamp through the sample. A parallel monitoring light beam from the fiber optic cable was maintained perpendicular to the test sample as it passed through the coated test chip sample and directed towards a receiving fiber optic cable assembly mounted on the spectrophotometer. The precise placement of the coated test chip sample in the sample cell was where the activated xenon arc beam and the monitoring light beam intersected, forming concentric circles of light. The angle of incidence of the xenon arc beam at the sample placement point was approximately 30° to perpendicular.

[0125] The response measurement of the change in optical density (ΔOD) from the inactive or decolorized state to the activated or colored state was determined by confirming the initial inactive transmittance, opening the shutter from the xenon lamp, and measuring the transmittance due to activation at selected time intervals. The change in optical density was determined according to the following formula. ΔOD = Log (10) (%Tb / %Ta) In the above ΔOD formula, %Tb is the transmittance percentage in the decolorized state, and %Ta is the transmittance percentage in the activated state. The ΔOD at saturation is 15 minutes after activation, and the fading half-life ("T1 / 2") value is the time in seconds until the ΔOD of the activated state of the photochromic material in the coating reaches half of the ΔOD at 73.4°F (23°C) at 15 minutes, after the activation light source has been removed.

[0126] The results of the tests and evaluations described above are summarized in Tables 2 and 3 below.

[0128] [Table 7]

[0129] The data summarized in Table 2 shows that the indenonaphthopyrane compound according to the present invention (having a (perfluoroalkyl)arylthio substituent at the 11th position) provides an improved fading rate compared to the comparative indenonaphthopyrane compound (having a (fluoroaryl)thio substituent at the 11th position) without significantly sacrificing the darkness of the activated state. The data summarized in Table 3 shows that the indenonenaphthopyrane compound according to the present invention, having various groups at the 11th and 7th positions, provides a faster fading rate.
