Abstract

Bidipyrrin-bridged macrocycles, prepared from NiII-bridged dipyrrinbased nanorings by intramolecular oxidative biaryl coupling reactions, yielded [2+4]-type ZnII-assisted stable twisted-ring dimers comprising two double helices. These [2+4]-type metal complexes can be optically resolved by chiral HPLC and exhibit tunable electronic and optical properties as a result of spring-like motions. The double helices behave as glue to connect two macrocycles and as the screws of hinges to form thermally responsive synchronized spring systems.
