showed that the absorption maxima of the compounds vary from 366 to 370 nm depending on the group bound to benzene rings. The maximum emission spectra of the compounds in dichloromethane were dependent on nature of groups in benzene ring. Furthermore, the compound 3b can be used to determine Cu2+ ion with high selectivity and a low detection limit in the DMF:H2O = 1:1 (v/v) solution.
通过查尔酮和5-芳基-2-肼基-1,3,4-噻二唑的反应合成了一系列新颖的1,3,5-三芳基吡唑啉衍生物,产率为43.3–84.7%。使用IR,1 H NMR和HRMS光谱以及X射线衍射分析对化合物的结构进行表征。在二氯甲烷,甲苯,乙腈,N,N-二甲基甲酰胺和四氢呋喃中研究了该化合物的吸收和荧光特性。结果表明,取决于与苯环结合的基团,化合物的最大吸收在366至370 nm之间变化。化合物在二氯甲烷中的最大发射光谱取决于苯环中基团的性质。此外,化合物3b可用于在DMF:H 2 O = 1:1(v / v)溶液中以高选择性和低检测限测定Cu 2+离子。
