A kind of iridium complex, synthesis method and application thereof

Abstract

The invention relates to an iridium complex. A synthesizing method of the iridium complex comprises the steps that a compound 1,3,3-trimethyl spiro[indoline-2,2'-(1,4)oxazine(2,3-f)(1,10)phenanthroline] and a bridge chlorine complex 2-iridium phenylpyridine are added in a react solvent to react under a nitrogen atmosphere at 100-150 DEG C, and reaction liquid is cooled to the room temperature; then, a saturated potassium hexafluorophosphate solution is added in the reaction liquid, the mixture is stirred evenly, dichloromethane is added for extraction, organic phases are collected, washing isconducted with distilled water, evaporation is conducted to remove the organic solvent, and thus a crude reaction product is obtained; petroleum ether and dichloromethane are adopted according to theratio of 3:1 to serve as mobile phases, the crude reaction product is separated and purified through a silica gel column, and thus the iridium complex is obtained. The iridium complex has excellent light stability, shows an excellent nonlinear optical effect at the laser of 532 nm, and can serve as a laser protection material to be applied to eye protection and precise optical device protection films.

Description

Technical field [0001] The invention relates to a novel cationic iridium complex and a synthesis method thereof, and belongs to the technical field of organic synthesis. Background technique [0002] Non-linear optical materials are materials whose optical properties depend on the intensity of incident light. Nonlinear optical materials can be applied to optical switches, photodetectors, optical memories, etc. (Angew ChemInt EdEngl 2009, 48(18), 3244-66.). After more than 50 years of research, various types of nonlinear optical materials have been discovered. For example, inorganic materials include KH 2 PO 4 , LiNbO 3 , CdSe, etc. Organic materials include porphyrin, polythiophene, etc. In addition, it has been found that carbon materials, graphene and carbon nanotubes have excellent nonlinear optical properties. Metal-organic complexes have the advantages of large nonlinear optical coefficient, fast photoresponse time, high photodamage threshold, easy modification of organic ...
