Abstract

A novel metal-organic frameworks (MOF) material, namely {Zn₃(bpybc)(imdc)₂·H₂O)}_n (1), (bpybc²⁻ = 1,1′-bis(4-carboxyphenyl)-4,4′ -bipyridinium cation, imdc³⁻ = 4,5-imidazole-dicarboxylic acid anion) has been successfully synthesized under solvothermal conditions. The synthesis utilized H₂bpybc·2Cl, 4,5-imidazole-dicarboxylic acid and Zn(NO₃)₂·6H₂O as the raw materials. Complex 1 not only exhibits reversible photochromic behavior but also features photocontrolled luminescence properties. Notably, complex 1 shows the sensing ability of Cr₂O₇²⁻. It has the capability to selectively detect ammonia vapor, undergoing a color change from orange to tan in response to ammonia vapors, thereby exhibiting certain sensing properties for ammonia vapor.

基于病毒配体的新型 MOF：光致变色、氨传感和 Cr2O72- 检测

在溶热条件下成功合成了一种新型金属有机框架（MOF）材料，即{Zn3(bpybc)(imdc)2-H2O)}n (1)（bpybc2- = 1,1′-双（4-羧基苯基）-4,4′-联吡啶阳离子，imdc3- = 4,5-咪唑二羧酸阴离子）。合成过程以 H2bpybc-2Cl、4,5-咪唑二羧酸和 Zn(NO3)2-6H2O 为原料。复合物 1 不仅具有可逆光致变色行为，还具有光控发光特性。值得注意的是，复合物 1 显示出了 Cr2O72- 的传感能力。它具有选择性检测氨蒸气的能力，在氨蒸气的作用下，颜色会从橙色变为棕褐色，从而显示出对氨蒸气的某些传感特性。
