摘要
One new chiral metal-organic coordination polymer,[Cd2（dpb）（H2hfipbb）2]n,was obtained under hydrothermal conditions of 1,3-di（pyridineyl）benzene（dpb） and 4,4＇-（hexafluoroisopropylidene）bis（benzoic acid）（H2hfipbb）. The title compound reveals a three-dimensional（3D） framework with two types of helical chains [Cd（COO）]n,which are linked each other to further form a double helical chain [Cd2（COO）2]n by sharing the same Cd（Ⅱ） ions. The dpb connects the double helical chains to generate a 3D framework. These unique structures were studied by single-crystal X-ray and other spectroscopy techniques. In addition,the luminescent,fluorescence lifetime and second harmonic generation efficiency properties in the solid state have been studied.
