Triphenylamine as an Electron/Energy Donor in a Supramolecular Zinc Tetraphenylporphyrin System

Abstract

The supramolecular systems containing an electron acceptor, zinc 5,10,15,20-meso-tetraferrocenylporphyrin and a pyridine-based triphenylamine as an electron/energy donor, has been investigated. Fluorescence and transient fluorescence spectra revealed that the axial coordinative complex performed a intramolecular photoinduced electron/energy-transfer from the triphenylamine to the porphyrin unit (phene-based triphenylamine used as a reference). Pyridine/phene-based triphenylamine derivatives were synthesized and characterized by ¹H NMR, IR and ESI-MS.
