Synthesis and Characterization of Nano-Crystals Molecular Hybrid Material with 3,3′,5,5′-Tetramethylbenzidine and Molybdophosphate

以3,3′,5,5′-四甲基联苯胺(TMB)与Keggin结构钼磷酸H3PMo12O40杂化,合成得到新型分子杂化材料,经元素分析及IRI、CP、XRD等手段表征,确定其分子结构为(TMB)3PMo12O40,TEM显示该分子杂化材料颗粒直径在40nm^60nm,分布均匀,属球形颗粒纳米晶,UV-vis和ESR谱证明(TMB)3PMo12O40分子杂化材料为电荷转移型超分子化合物,并具有显著的光敏性和电催化活性。

A novel nano-erystal molecular hybrid material has been synthesized with 3,3′, 5,5′-tetramethylbenzidine （short for TMB） and Keggin structure heteropoly acid H3PMo12O40. The formula of this hybrid material was characterized to be （TMB）3PMo12O40. TEM images showed that the organic-inorganic hybrid material is a nano-crystal in size of 40- 60nm. IR, UV-vis and ESR spectra indicate that there is strong electron interaction between TMB and molybdophosphate forming a charge-transfer supermolecule hybrid material, which shows significant photosensitive and electrocatalytic properties.
