新型金属锌有机膦酸盐的合成与光谱研究
Syntheses and Spectral Study of Novel Metal Zinc Organic Phosphonate
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)]·H2O 2。 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-Vis DRS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350 nm激发, 在412和520 nm左右出现两个宽带发射峰, 而化合物2在336 nm激发下只在398 nm处出现宽带发射峰。
Abstract
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.
