Photoluminescent sensing of nitrobenzene, Fe(III) and CrO42− ions indicates that 1 could be a candidate for developing selective luminescent sensors for these species. Theoretical calculations have been performed to gain insight into the possible mechanism of quenching effect in emission on addition of nitrobenzene in 1 which supports the mechanism operating through ground state charge transfer between 1 and
摘要 A Cd(II)-MOF, [Cd(L)(4,4'-bipy)]·H2O·DMF}n (1) (L = 烟酸 (2,4-dihydroxybenzylidene)-hydrazide and 4, 4'-bipy = 4,4'-bipyridine),已通过微量分析、FTIR、TGA 和单晶 X 射线衍射进行合成和表征。此外,进行粉末 X 射线衍射以检查合成化合物的相纯度。单晶 X 射线衍射表明 1 具有二维网格网络。硝基苯、Fe(III) 和 CrO42− 离子的光致发光传感表明 1 可能是为这些物种开发选择性发光传感器的候选者。已经进行了理论计算以深入了解在 1 中添加硝基苯时发射猝灭效应的可能机制,这支持通过 1 和硝基苯之间的基态电荷转移起作用的机制。
