以螺吡喃衍生物原位合成的席夫碱配体的铜配合物的制备及表征

Preparation and Characterization of Copper Complexes of Schiff Base Ligands Synthesized In Situ from Spiropyran Derivative

在Cu^(2+)存在条件下,利用N‑羟乙基‑3,3‑二甲基‑6‑硝基吲哚啉螺吡喃分别与乙二胺分子或1,3‑丙二胺分子(1,3‑diaminopropane,1,3‑DAP)发生原位反应,得到了席夫碱配体双‑((2‑(甲基亚胺甲基)‑4‑硝基苯酚))阴离子(L_(1))或2‑((3‑胺基丙基亚胺)‑甲基)‑4‑硝基苯酚阴离子(L_(2))的铜配合物[Cu(L_(1))](1)和[Cu(L_(2))(1,3‑DAP)]NO_(3)(2)。用红外光谱、单晶X射线衍射和粉末X射线衍射对2种配合物进行了相关表征。在降解有机染料分子的过程中,观察到2种配合物具有一定的光催化性能。

By virtue of Schiff base ligands bis(2‑(methyliminomethyl)‑4‑nitro‑phenol)dianion(L_(1))/2‑((3‑aminopropylimino)‑methyl)‑4‑nitro‑phenol monoanion(L_(2))that derived from photochromic molecule 2‑(3',3'‑dimethyl‑6‑nitrospiro(chromene‑2,2'‑indolin)‑1'‑yl)ethanol,two metal‑organic complexes[Cu(L_(1))](1)and[Cu(L_(2))(1,3‑DAP)]NO_(3)(2)have been successfully fabricated through in situ ligand reaction in the presence of Cu^(2+).These complexes were characterized by IR,single‑crystal X‑ray diffraction,and powder X‑ray diffraction.Additionally,certain photocatalytic properties of the two complexes for the degradation of organic dye molecules have been observed.CCDC:2053028,1;2104827,2.
