Synthesis and self-assembly properties of fullerene/porphyrin-phthalocyanine and fullerene/bis-phthalocyanine triads

摘要

In this work, we report on the synthesis and characterization of two fulleropyrrolidines bearing porphyrin/phthalocyanine and bis-phthalocyanine tweezers. The self-assembly properties in different solvents have been investigated by AFM and SEM. When deposited on surface from dichloromethane solutions, the fullerene derivatives formed aggregates of ca. 4-8 nm in height while hollow nanospheres with diameters of ca. 300-1000 nm are obtained from crystallization attempts.
