摘要
通过水热合成法,利用Zn(CN)2,2,2’-联吡啶合成出一种新颖的复配物[Zn(bipy)_3][Zn(CN)_4]·2H_2O(1),它的特点是通过复杂的氢键作用,将一种结构新颖的线性四聚体水簇和[Zn(CN)_4]_2-负电基团连接组装成一种二维超分子网络.并对1进行了包括单晶X-射线衍射、红外、热重以及荧光发射在内的表征与分析.研究发现在室温下310 nm的紫外光激发下,1表现出强烈的荧光发射性质,且发射光波长为437 nm,与绿光非常接近.
A hydrothermal reaction of Zn(CN)2, 2,2’-bipyridine(bipy)afforded a novel multicomplex, [Zn(bipy)3][Zn(CN)4]·2H2O(1), which features a 2D supramolecular network assembled from unprecedented linear water tetramers and anionic [Zn(CN)4]2- moieties through intricate hydrogen bonding interactions. Single-crystal X-ray diffraction, FT-IR, thermogravimetric analysis and photoluminescence spectrum of 1 also have been discussed. 1 exhibits strong photoluminescence maximized at 437 nm upon 310 nm excitation at ambient temperature, of which is close to that of the greenish light.
