we aim to modify the photochromic properties of anils using a crystal engineering approach. Previous work has shown cocrystallization to alter the photochromic behavior of anils. Here, a full screening of 15 anil derivatives (including 8 newly described anils) with 21 coformers (carboxylic acids, amides, and halogenated benzene derivatives) was performed, resulting in 89 new anil cocrystals.

在这项贡献中,我们旨在使用晶体工程方法来修改茴香的光致变色特性。先前的工作表明共结晶可改变指甲的光致变色行为。在这里,用21种共形成物(羧酸,酰胺和卤代苯衍生物)对15种茴香衍生物(包括8种新描述的茴香)进行了全面筛选,得到了89种新的茴香共结晶。大量的结果允许对复杂的光致变色机理进行统计上有效的洞察,从而提供连续现象的证据,而不是经典的二元光致变色/非光致变色现象。该贡献中发现的“弱光致变色化合物”的发现为这一点提供了支持。所有结果都证实了烯醇-亚胺是必要条件,减少涉及目标部分的短接点数量是微调特性的有趣方法,因为它既影响电子又影响结构。根据这种“连续假设”,已经对二面角的作用进行了探索,并显示其与光致变色的强度有关,而不是决定其发生的原因。此外,在这一贡献中,我们提出了一种解释DRS(漫反射光谱)数据的新颖方法。已经探究了二面角的作用,并表明它与光致变色的强度有关,而不是决定其发生的原
