许多光电子有机材料是基于具有含杂原子的电子供体的供体-受体（D-A）系统。在这里，我们介绍了一种新的分子设计的全碳弯曲的oligoparphenylenes作为供体，这导致在生成独特的形状持久的D-A大环。合成了两种类型的受体插入的环对苯撑。这些大环化合物由于其D-A特性而显示出正的溶剂化荧光变色性质，这一点已被理论和电化学研究所证实。
Many optoelectronic organic materials are based on donor-acceptor (D-A) systems with heteroatom-containing electron donors. Herein, we introduce a new molecular design for all-carbon curved oligoparaphenylenes as donors, which results in the generation of unique shape-persistent D-A macrocycles. Two types of acceptor-inserted cycloparaphenylenes were synthesized. These macrocycles display positive solvatofluorochromic properties owing to their D-A characteristics, which were confirmed by theoretical and electrochemical studies.
