Metal iridium-triazole crystal-graphene oxide ternary nonlinear optical material and preparation method thereof

The invention belongs to the field of a nonlinear optical material, and discloses a metal iridium-triazole crystal-graphene oxide ternary nonlinear optical material and a preparation method thereof. An iridium dichloro bridge compound and an organic auxiliary ligand of 4-amidogen-3,5-bi-(4-pyridine)-1,2,4-triazole are synthesized into a metal iridium complex; then, the metal iridium complex and the graphene oxide are used to be synthesized into the metal iridium-triazole crystal-graphene oxide ternary nonlinear optical material; the metal iridium complex is connected onto the graphene oxide surface in a covalent form. The characteristic combination of the metal iridium complex and a nanometer functional material is realized; a Z-scanning technology shows that the composite material has higher nonlinear absorption response on metal iridium complex monomers. 本发明属于非线性光学材料领域，公开了种金属铱-三氮唑晶体-氧化石墨烯三元非线性光学材料及其制备方法。本发明以铱二氯桥化合物和有机辅助配体4-氨基-3,5-二-(4-吡啶)-1,2,4-三氮唑合成金属铱配合物，然后利用金属铱有机配合物和氧化石墨烯合成金属铱-三氮唑晶体-氧化石墨烯三元非线性光学材料，金属铱配合物
