spectra. The photochromic property of the synthesised compound investigated under 365 nm UV irradiation can be observed by solid state absorption and fluorescence spectra. The kinetic study showed that the photochromic reaction was of the pseudo-first-order. The photo-isomerisation was due to photo-induced intermolecular hydrogen bonding, which resulted in enol to keto transformation. The molecular switching
一种新的席夫碱化合物4-[[((5-羟基-3-甲基-1-苯基-1 H-吡唑-4-基)亚甲基]氨基] -1,5-二甲基-2-苯基-2,3合成并通过元素分析和LC-MS,FTIR和1 H NMR光谱表征了-dihydro-1 H -pyrazol-3-one(I)。可以通过固态吸收和荧光光谱观察在365 nm UV辐射下研究的合成化合物的光致变色性质。动力学研究表明光致变色反应是伪一级反应。光异构化是由于光诱导的分子间氢键,从而导致烯醇转化为酮。分子开关行为是在溶液中三种不同的系统研究了两个输入(OH -和Ag +),(OH -和Cd 2+)和(OH -和Th 4+)基于UV吸收光谱。它在碱性介质中分别表现出XNOR,AND和NOR对Ag +,Cd 2+和Th 4+的逻辑行为。
