The photophysics, photochemistry, and kinetics of two major families of photochromic hydrazones have been studied by means of microsecond and nanosecond laser flash techniques. In addition, picosecond fluorescence spectroscopy was used in some cases in order to aid in the elucidation of the photochromic mechanims. Several derivatives of benzaldehyde (hydrazones) have been studied. All of them showed
已经通过微秒和纳秒激光闪光技术研究了两大类光致变色腙的光物理、光化学和动力学。此外,在某些情况下还使用了皮秒荧光光谱,以帮助阐明光致变色机制。已经研究了苯甲醛(腙)的几种衍生物。它们都表现出反顺式异构化。发现 2-羟基苯甲醛腙的衍生物发生源自羟基的分子内质子转移
