Coordination and Spectral Properties of Oxa-Substituted Tetraphenylporphyrin Derivatives

Using theoretical conclusions from the Gouterman four-orbital model, a detailed analysis of the formation of absorption and fluorescence spectra of free bases and their zinc complexes has been performed for 5,10,15,20-tetraphenyl-21-oxaporphyrin and 5,10,15,20-tetraphenyl-21,22-dioxaporphyrin. The i...

Description
Summary:Using theoretical conclusions from the Gouterman four-orbital model, a detailed analysis of the formation of absorption and fluorescence spectra of free bases and their zinc complexes has been performed for 5,10,15,20-tetraphenyl-21-oxaporphyrin and 5,10,15,20-tetraphenyl-21,22-dioxaporphyrin. The influence of the symmetry of the molecule on the position and shape of the bands in the electronic absorption and fluorescence spectra is shown. The kinetic parameters of the reactions of complexation of oxasubstituted derivatives of 5,10,15,20-tetraphenylporphine with d -metal salts (Cu(II), Zn(II), and Co(II)) at 288–308 K have been determined for the first time. The kinetic data obtained for oxasubstituted derivatives have been compared with results obtained for their classical analogue, tetraphenylporphine.
