Abstract

A general assembly approach is developed to construct hierarchically tunable helical superstructures from an achiral porphyrin-incorporated alkoxysilane. The resulting superstructures can be controlled from film, rice, spindle, ribbon, to fiber in morphology and from nonhelical to helical in structure at a multiscale with excellent optoelectronic, electrical, and thermal properties.
