A series of robust organoboranes with electronicallytunable functionality of B/N Lewis pairs has been achieved. These compounds feature a B/N-containing core in which the interactions between the B and N atoms are modulated as a result of the structural flexibility of the nonconjugated backbone. Examination of the substituent effects of the Lewis base moiety reveals that bulky or aryl substituents
已经实现了一系列具有电子可调性的B / N Lewis对电子的功能强大的有机硼烷。这些化合物的特征是含B / N的核心,其中B和N原子之间的相互作用由于非共轭主链的结构灵活性而受到调节。对路易斯基团部分的取代基效应的研究表明,庞大的或芳基的取代基有利于B-N键响应外部刺激(例如热或机械压力)的动态转换,从而导致发射颜色的调制。这项工作为基于可调电子交互的新型可切换材料设计提供了一种新的,直接的概念证明。
