[0032] Determination of third-order nonlinear properties of 5,15-ferrocenyl-10,20-diphenylporphyrin

[0033] The nonlinear absorption and nonlinear refraction of 5,15-ferrocenyl-10,20-diphenylporphyrin were measured by Z-scan technique in pure chloroform with a concentration of 10 -4 mol / L -1 . The thickness of the cuvette containing the sample in the experiment is 1mm, and the beam waist radius at the focal point of the lens is w 0 is 40μm, the linear transmittance S of the small hole is 0.1, and the optical power density at the focal point of the lens is 7.593×10 9 W / cm 2. The entire system was calibrated with carbon disulfide prior to measurement. We under the same conditions for the pure solvent CHCl 3 Measurements were performed to confirm that the measured curves were all derived from the properties of the compounds and not influenced by the solvent.

Description

technical field [0001] The invention relates to the preparation and application of ferrocenyl porphyrin molecules, and belongs to the technical field of organic nonlinear optical materials. Background technique [0002] With the advent of lasers, nonlinear optics (NLO) has also developed. Nonlinear optics mainly studies the interaction between strong light (such as laser) and matter. When the light reaches a certain intensity, the absorption of light by matter no longer conforms to the laws given by traditional optics, and its absorption coefficient will change with time. Vary with changes in light intensity. Due to the great potential application value of nonlinear optical materials in the fields of optical communication, high-speed photoelectric information processing, high-density data storage, short optical pulse generation, spatial light modulation, and all-optical switches, the research on nonlinear optical materials has become the current one of the cutting-edge top...
