| Abstract: | 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. |
