Abstract:

A series of peripherally substituted free base corroles (1, 2, 3, 4) and their gallium complexes 1-Ga(Py), 2-Ga(Py), 3-Ga(Py), 4-Ga(Py) were synthesized and characterized by proton nuclear magnetic resonance (1H NMR), UV-visible (UV-Vis) spectroscopy and electrospray ionization mass spectra (ESI-MS). The UV-visible spectra, steady state fluorescence spectra,and time resolved fluorescence spectra of the free base corroles and their gallium complexes were recorded in different solvents. Fluorescence lifetimes were obtained by fitting fluorescence decay kinetics curves using a single exponential simulation. The effects of non or weak polar solvents on the UV spectrum of gallium corrole were fitted to the Bayliss equation and the non-radiative energy loss hc(ν1A-νF) of gallium corrole and F(n) showed a linear correlation.
