| 摘 要： | 通过水热法合成了两种锌配位聚合物{Zn(ic)(bip)]·2H2O}n (1)和Zn(ic)(bpe)]n (2)(H2ic=衣康酸,bip=3,5-二(1-咪唑基)吡啶,bpe=1,2-二(4-吡啶基)乙烯),并通过X射线单晶衍射和元素分析对其结构进行了表征.配合物1和2均为含有一维金属-羧酸链的二维(4,4)格子层结构.此外,对它们的热重、粉末X射线衍射和固体荧光性能进行了考察.与配体bip相比,1的发射光谱发生了明显的蓝移(~78 nm),可能归因于配体到金属的电荷转移;2显示与游离的bpe配体相似的荧光性质,轻微的红移可能是因为与金属离子之间的配位作用导致的.

| Abstract: | Two zinc coordination polymers {Zn(ic)(bip)]·2H2O}n (1) and Zn(ic)(bpe)]n (2) (H2ic=itaconic acid, bip=3,5-bis(1-imidazoly)pyridine, bpe=1,2-bi(4-pyridyl)ethylene) were synthesized hydrothermally and character-ized structurally by single-crystal X-ray diffractions, elemental analysis. Both complexes 1 and 2 display 2D (4,4) grid layers containing 1D metal-carboxylate chains. Thermogravimetric Analyses (TGA), powder X-ray diffractions (PXRD) and fluorescence properties for compounds 1 and 2 are also investigated. The solid state fluorescence spectra indicate that the emission spectrum of complex 1 shows obvious blue shift (~78 nm) compared to free bip coligand due to the ligand-to-metal charge-transfer (LMCT) effect. The compound 2 shows similar emission spectrum to the free bpe ligand, but the slight red-shift may be attributed to the complexation effect between the bpe molecule and Zn atoms.
