extensive spectroscopic and computational studies, we envisaged the factors controlling near‐quantitative photoisomerization in both the directions (bistability) and the thermal stability of the metastable states. Furthermore, we also evaluated the impact of designs in obtaining reversible photo‐responsive sol‐gel phase transitions, solvatochromism, photo‐ and thermochromism.
光响应性分子系统在多个光电继电器Ç 3 -对称设计具有巨大的应用潜力。这种分子系统的设计部分至关重要,因为它会影响与光电开关相关的若干特性。为了调整和评估设计与属性的关系,我们合成了18个三脚架系统,其核心,连接子,连接性和偶氮(杂)芳烃光电开关均发生了变化。通过广泛的光谱和计算研究,我们设想了在亚稳态的方向(双稳性)和热稳定性方面都控制近定量光异构化的因素。此外,我们还评估了设计对获得可逆的光响应溶胶-凝胶相变,溶剂变色,光变色和热变色的影响。
