calcium signals by reversibly binding and releasing calcium ions in response to light. Substituent changes on the largely unexplored photochromic bisbenzospiropyran scaffold led to significant changes in thermal fading rates in several organic solvents. Excellent correlations have been found between fading rates and empirical Hammett constants as well as calculated ground-state energies. These correlations
光致变色分子的一种新型应用是通过响应于光可逆地结合和释放钙离子来模仿生理振荡的钙信号。在很大程度上未开发的光致变色双苯并螺旋吡喃支架上的取代基变化导致几种有机溶剂中的热褪色速率发生了显着变化。已发现衰落速率与经验Hammett常数以及计算出的基态能量之间具有极好的相关性。这些相关性可用于改善支架设计。
