    • Abstract

       

      Several research activities in the different topics of photochemistry, photophysics and photobiology are being conducted. Trends of research in Egyptian institutions include—

      (A) Preparative organic photochemistry. Studies on the photolysis of different organic compounds have been carried out. Moreover, research work is aimed at investigating the utilization of solar energy in the photooxidation of inexpensive organic compounds to produce precious ones of pharmaceutical interest.

      (B) Research work is performed in different areas related to fluorescence spectrometry and laser dyes. The first field involves studies on the essential photophysical properties of some groups of electron-donor-acceptor (EDA) molecules like the styrylcyanine type and coumarins. Currently, research is pursued along the following lines: (1) Solvatochromism and photochromism of these dyes with special reference tocis-trans quantum yield determination. (2) Molecular aggregation of functionalized surfactant cyanines and their fluorescence quenching. (3) The analytical use of these dyes and others as fluorescent probes for various systems of biological and industrial importance. Another important field of research is the field of photochemical and emission characteristics of new laser dyes of the diolefinic type and pyrazinyl Schiff-base derivatives.

      Research work also includes photochemical studies on some polymeric materials and photoconductivity.
