采用一种新方法得到一维配位聚合物[Zn(CH3COO)2(4,4′-bipy)]n(1)。配合物1的晶体结构和荧光性质已经有详细报道,但光致变色性质还没有相关的研究工作发表。通过研究化合物1在光照前后的紫外吸收光谱和顺磁共振谱,表明化合物1具有电子转移光致变色性能。实验结果验证了我们提出的利用非光致变色单元设计电子转移光致变色材料的新方法是有效可行的。 One-dimensional coordination polymer [Zn (CH3COO) 2 (4,4’-bipy)] n (1) was obtained by a new method. The crystal structure and fluorescence properties of complex 1 have been reported in detail, but the photochromic properties have not been published yet. The UV absorption spectra and paramagnetic resonance spectra of compound 1 before and after irradiation show that compound 1 has electron transfer photochromism. The experimental results validate our proposed new method of designing electron transfer photochromic materials using non-photochromic cells.
