New Metallo-Porphyrins for Solar Energy Conversion

Abstract

Tetrapyrrole macrocycles play important roles that serve nature in various ways for energy conversion. Under such context, the tetra-aryl porphyrins derivatives are known as one of the most efficient sensitizers in solar energy conversion. The investigations of spectral properties of the metallic complexes (rhodium and ruthenium) of 5,10,15,20-p-tetra-aryl porphyrins are achieved by UV-Vis and FT-IR analysis. The surface morphology of the samples was probed by scanning electron microscopy (SEM, SEM+EDS). The investigation results of the studied porphyrins revealed the perspective for potential photochemical applications of such materials.
