A new meso–meso directly-linked corrole–porphyrin–corrole hybrid: synthesis and photophysical properties

Abstract

A first example of a directly-linked corrole–porphyrin–corrole (Cor–Por–Cor) triad has been targeted and synthesized. The new hybrid has been fully characterized by ¹H NMR, ¹⁹F NMR and 2D NMR spectroscopy. The fluorescence quantum yield of the triad is three times higher than that of meso–meso directly linked porphyrin trimers. All the three chromophores assume a near orthogonal geometry with respect to the neighbour.
