| 摘 要： | 用时间相关光谱法研究了水杨醛缩胺类Schiff碱光致变色的性质,发现分子共轭体系大小和分子骨架刚性等因素对光致变色性质存在规律性的影响.共轭体系越大,发生光致变色的速率越小;分子骨架的刚性越大,化合物越难发生光致变色;反之,则光致变色较容易进行.

| Abstract: | The photochromism of salicylaldehyde-derived Schiff bases were studied from a view-point of structure-property relationship. It was found that the π-conjugated system and the flexibility of the molecular skeleton play an important role in the determination of the photochromic behavior. The molecules with smaller π-conjugated systems or flexible skeletons are easy to undergo the photochromism. |
