Abstract
The interaction of metallo derivatives of tetraphenylchlorin (TPC) and octaethylporphyrin (OEP) with 2,4,7-trinitrofluorenone (TNF) is described in terms of 1 : 1 molecular complexes. The binding constants vary as CuOEP>ZnOEP>CuTPC>ZnTPC and this variation is accounted in terms of the structure of the macrocycle and the substituents presen on it. ESR studies of the complexes reveal that the π-complexation results in changes in the electronic structure of the central metal ion. The magnitude of different proton shifts of the acceptor in 1H NMR spectra of the complexes are used to arrive at the possible solution structure of the complexes.
