Abstract

Abstract: The in situ preparation and the full spectroscopic characterization of corrole - gold nanoparticles (AuTPFCS) are reported. The synthetic approach to these nanoconjugates involved the reaction of a mercaptocorrole (TPFCSH) with chloroauric acid under reductive conditions. Fluorescence quantum yields and time resolved lifetimes showed a significant quenching of the mercaptocorrole after its covalent coupling to the gold nanoparticles in acetonitrile and in toluene. Irradiated samples of AuTPFCS with a Nd:YAG laser in toluene solution revealed the distribution of larger nanoparticles from 3.1 to 11 nm viewed by TEM images.
