Abstract

Absorption spectral changes observed during sodium mirror reduction of tribenzotetraazachlorin–fullerene (TBTAC–C60) conjugates have clarified that electronic communication between the TBTAC and C60 moieties is switched off upon reduction of the conjugates. Spectroscopy has suggested that the anionic species retains its aromatic character.

Abstract

A tribenzotetraazachlorin (TBTAC)-C(60) conjugate having three 15-crown-5 units as substituents, , has been synthesized, and the electronic and supramolecular structure modulations in the presence of Na(+) or K(+) have been elucidated by means of massmetric and spectroscopic techniques.
