Embodiment 1

[0029] Dissolve 25 g of analytically pure 8-hydroxyquinoline in 100 mL of absolute ethanol, add NaOH solution (50 g of NaOH dissolved in 70 mL of deionized water), mix well and cool, then add dropwise chloroform (25 mL, drop over 1 hour). After the chloroform was added dropwise, the temperature was raised and stirred under reflux for 18 hours. Evaporate excess chloroform and ethanol on a rotary evaporator, dissolve the remaining residue in 600mL deionized water, adjust the pH value to 5-6 with dilute hydrochloric acid, a precipitate is formed, filter it with suction and wash it with deionized water, and remove the precipitate The material was dried in an oven at 80°C. Grind the dried solid into powder, extract with petroleum ether with a boiling range of 90-120°C for 48 hours in a fat extractor, cool the extract, collect the precipitate by filtration, and recrystallize with absolute ethanol. 2.1 g of 5-formyl-8-hydroxyquinoline are obtained. For mass spectrometric characteri...

Embodiment 2

[0035] 0.115g 3,5-diamino (8-hydroxyquinoline)-benzoic acid, 0.0182g5-(4-N, N dimethylaminobenzene) azo-8-hydroxyquinoline prepared by Example 1 and Add 0.06g of anhydrous ferric trichloride to 20mL of methanol, stir vigorously until the solution is clear.

[0036] Films were prepared by spin coating method. Using Z-scan technology to obtain the nonlinear refractive index n of the material at a wavelength of 1064nm 2 =-1.84×10 -8 esu. See Figure 6.

Abstract

The invention, pertaining to the field of non-linear optical materials, relates to a preparation method for a coordination polymer doped with optical non-linear chromophores. The invention adds 5-formyl-8-hydroxyquinoline and 3, 5-diaminobenzoic acid by molar weight ratio of 2: 1 to toluene, circle heats the mixture for more than 48 hours and then washes the mixture with alcohol and trichloromethane after filtration; mixes the non-linear chromophore with 8-hydroxyquinoline according to the molar weight proportion required to prepare non-linear chromophore modified 8-hydroxyquinoline by thermal chemical method; adds the 5-formyl-8-hydroxyquinoline and the non-linear chromophore modified 8-hydroxyquinoline to methanol and then adds sufficient coordination salt required for coordination under severe stirring condition, waits for the solution to clarify. The optical non-linear chromophore of the invention is connected with the coordination polymer by a coordination bond. The invention hasthe advantages of good stability, simple process and low cost without phase separation.

Description

technical field [0001] The invention relates to a preparation method of a doped optical nonlinear chromophore coordination polymer, which belongs to the field of nonlinear optical materials. Background technique [0002] At present, due to their potential roles in the fields of all-optical switching, optical conversion, optical signal processing, and optical communication, materials with large nonlinear susceptibility and fast third-order nonlinear response have attracted more and more attention. Among them, organic polymers, Organometallic coordination polymers are becoming a research hotspot. [0003] Organic polymer nonlinear optical materials usually have nonlinear chromophores with large π-conjugated structures. By designing and exchanging these chromophores, the nonlinear properties of materials can be changed, which is conducive to the exploration of excellent nonlinear optical material. And most polymers can be prepared by liquid phase treatment (spin coating metho...
