Metalloporphyrins thin films as optical receptors for organic gases

Abstract

Metalloporphyrins are conjugated-aromatic organic chemicals which play a peculiar role in some biological activities of the living creature, such as metabolism and energy transfer, and present as model for a complex biological system. These chemicals have been widely used as active receptor for various kinds of analytes, particularly organic gases and demonstrated a broad range of selectivity properties. This paper reports the use of the optical technique to investigate the receptive behavior of these chemicals towards the presence of several gaseous molecules. It was found that the molecular structure of these chemicals, particularly the central metal atom and the molecular periphery, play an important role in the enrichment of their selectivity features through two prominent activities; electron donating-accepting and Van der Wall binding. The interaction with the gaseous molecules through the two possible mechanisms may create the change in the symmetry of the electron cloud surrounding the molecular skeleton. Hence, the optical properties of these compounds change and the transduction process occurred. The sensing sensitivity of these chemicals was also found to depend on the bulk size of the molecular layer and the microstructure of the thin films surface.
