Abstract:

Under solvothermal conditions,Cu(CF3COO)2·xH2O was used as a soluble copper salt, and thiophene?2,5?dicarboxylic acid (H2tdc) as a linear ligand, which reacted with 1,10?phenanthroline (phen) and 2,2′?bipyridine (bipy) respectively,to synthesize two one?dimensional chain compounds:[Cu(tdc)(phen)] n1) and [Cu(tdc)(bipy)] n ·DMF (2).The structures of the synthesized compounds were characterized by single?crystal X?ray diffraction(SC?XRD).The compositions of the compounds were analyzed by polycrystalline X?ray diffraction and Fourier infrared spectroscopy.The performances of the compounds were studied through photocurrent response tests and solution stability tests.The results show that the asymmetric structural unit of compound 1 is extremely similar to that of compound 2,with both containing the same [Cu(tdc)] structural unit. Both compounds exhibit photochemical stability,but they show different photocurrent response values,which is attributed to the different surface?modifying ligands (phen and bipy) in the two compounds.

摘要:

在溶剂热条件下,以Cu(CF3COO)2·xH2O为可溶性铜盐、噻吩?2,5?二羧酸(H2tdc)为线性配体,分别与1,10?菲罗啉(phen)和2,2′?联吡啶(bipy)反应,合成了一维链状化合物[Cu(tdc)(phen)] n1)和[Cu(tdc)(bipy)] n ·DMF(2);通过单晶X?射线衍射技术(SC?XRD)对化合物的结构进行了表征;通过多晶X?射线衍射和傅里叶红外光谱对化合物进行了组成分析;通过光电流响应测试和溶液稳定性测试对化合物的性能进行了研究。结果表明,化合物12的不对称结构单元极其相似,都含有相同的[Cu(tdc)]结构单元;化合物12都具有光化学稳定性;在不同的表面修饰配体phen和bipy的作用下,化合物12表现出不同的光电流响应值。
