New functions of metal-Schiff Base compounds as photoreactor

1. Schiff基地的第一个过渡金属复合体的光子反应已被调查。Manganese（III）和VO（IV）的N， N'-bis（salicylidene）phenylenidamine被发现可以被可见光激活，Schiff base ligand的光化结果。The products were separated by HPLC and？terized to be highly fluorescent 2-（2-hydroxyphenyl）benzimidazole byイイD11イエD1H，イイD113イエD1C NMR。反应机制是通过各种方法来研究的。《孟加拉邦的形成》（II）被EPR观察到，但没有有机基被发现。However，摄影效果是由激进清道夫的补充所颁发的。Schiff基地配体本身对光氧化不起作用，但在固体状态下发现了高通量。荧光特性在详细情况下进行了调查，包括薄膜的特性。芒果的光子作用（III）-Schiff base应用于DNA的光子学。5-（三甲基氨基甲基）-衍生物与DNA紧密结合，并通过可见光的辐照清除DNA。反应条件是在详细情况下进行调查的。在与这一关系中，铜（II）-多胺复合体的羟基DNA筛选也被调查。

1. Photoreaction of 1st transition metal complexes of Schiff bases was investigated. Manganese(III) and VO(IV) complexes of N, N' -bis(salicylidene)phenylenediamine were found to be activated by visible light, results in the photocyclization of Schiff base ligand. The products were separated by HPLC and characterized to be highly fluorescent 2-(2-hydroxyphenyl)benzimidazole by ィイD11ィエD1H, ィイD113ィエD1C NMR. The reaction mechanism was investigated by various methods. The formation of manganese(II) was observed by EPR but no organic radical was detected. However, the photoreaction was retarded by the addition of radical scavenger. Schiff base ligand itself was inactive to the photocyclization, but found to be highly fluorescent in the solid state. The fluorescent property was investigated in detail including thin film's property.The photoreaction of manganese(III)-Schiff base was applied to the photocleavage of DNA. 5-(trimethylammoniomethyl)-derivatives strongly binds with DNA and cleaved DNA by irradiation of visible light. The reaction conditions were investigated in detail. In relation to this, hydrolytic DNA scission by Cu(II)-polyamine complexes was also investigated.
