摘要

A face-to-face porphyrin dimer, (H _(2) P) _(2) “porphyrin tweezer”, was explored as a photo- and redox-responsive host for the molecular recognition of an azafullerene ( C _(59) N ) derivative bearing an amphoteric pentafluoroquinoline ( FQ ) domain. The intramolecular electronic coupling between the FQ substituent and the C _(59) N cage, within the newly synthesized C _(59) N-FQ dyad was evaluated, while the neutral and protonated form of the covalently attached FQ moiety were utilized as recognition motifs for the (H _(2) P) _(2) tweezer. Complementary photophysical and electrochemical techniques were applied to investigate the electronic communication between the porphyrin-dimer (H _(2) P) _(2) tweezer and the azafullerene cage as mediated by the FQ unit.
