摘　　要：通过水热法合成了Zn的两种新型有机膦酸盐,Zn(4,4’-bipy)(HBCP)1和[Zn2(phen)2(BCP)(H2BCP)].H2O2。其中化合物1为二维结构,Zn2+采用四面体配位方式,而化合物2为零维结构,Zn2+有五配位和六配位2种的配位方式。还利用了一维FTIR、热微扰下的二维IR相关光谱、Fluorescence和UV-VisDRS光谱等研究手段对化合物进行了研究,探讨了其结构与性能的关系,发现了化合物1以350nm激发,在412和520nm左右出现两个宽带发射峰,而化合物2在336nm激发下只在398nm处出现宽带发射峰。Two novel Zn2＋ organic phosphonate Zn（4,4′-bipy）（HBCP） 1 and [Zn2（phen）2（BCP）（H2BCP）]·H2O 2 were hydrothermally synthesized.The compound 1 is with two-dimensional layer framework whereas the compound 2 is zero-dimensional structure.The Zn2＋ion is four-coordinated in compound 1 while five or six-coordinated in compound 2.The relationship between their properties and structures was studied by using FTIR,two-dimensional （2D） correlation infrared spectroscopy under thermal perturbation,fluorescence and UV-Vis DRS spectrum etc.Upon light excitation at 350 nm,the compound 1 exhibits luminescence with a strong wide emission at 412 nm and a weak emission at 520 nm,while the compound 2 exhibits luminescence with a wide emission only at 398 nm under light excitation at 336 nm.
