Abstract

Singlet− singlet energy transfer in self-assembled via axial coordination of imidazole- appended (at different positions of one of the meso-phenyl entities) free-base tetraphenylporphyrin, H2PIm, to either zinc phthalocyanine, ZnPc, or zinc naphthalocyanine, ZnNc, dyads is investigated in noncoordinating solvents, o-dichlorobenzene and toluene, using both steady-state and time-resolved transient absorption techniques. The newly ...
