Lanthanide Porphyrin Complexes: Synthesis and Properties

Abstract

A new meso-substituted unsymmetrical porphyrin, 5-(4-myristyloxy)phenyl- 10,15,20-triphenyl porphyrin, and a series of its hydroxy lanthanide complexes, (lanthanide ions: Gd, Tb, Dy, and Ho) were synthesized and characterized by elemental analyses, molar conductances, UV-Vis, IR and ¹H NMR spectra. Their luminescent properties are studied by emission spectra. Q (0-0) fluorescence bands of the complexes are in the region 649–650 nm and Q (0-1) bands 714–715 nm. Quantum yields (Φf) of Q band for the complexes are in the range 0.00151–0.08433 and ligand 0.07459.
