Efficient energy transfer between coronene-modified permethyl-β-cyclodextrins and porphyrin for light induced DNA cleavage

Abstract

A novel supramolecular assembly was constructed by the noncovalent complexation of hexa-cata-hexabenzocoronene modified permethyl-β-cyclodextrins with tetrasodium tetraphenylporphyrintetrasulfonate in water, exhibiting highly efficient excited energy transfer behaviors and a promising DNA photocleavage ability.
