Advanced Research on New Materials Based on Pi-Conjugated Molecules. New materials based on pi-conjugated molecules for optoelectronic applications. Experimental and theoretical studies

      Аннотация: Materials based on pi-Conjugated molecules have attracted a considerable attention as a novel class of semi-conductors and are frequently studied because of their interesting optical and electronic properties which make them a good candidate for Opto-electronic applications. Because the importance of this type of materials in science and technology, a considerable effort has been made in their physico-chemical properties and modeling analysis and intensive research works stimulated by the above mentioned discoveries not only gave rise to a Nobel Prize (2000) in chemistry, but also to the several papers, devoted to the synthesis, characterization, theoretical studies and processing of these new generations of organic semi-conductors. It is difficult to prepare a review covering in details various aspects of these materials (design, synthesis, characterization and properties)We will, therefore, concentrate our discussion in this work on the different interesting papers published by our research group in several international journals.
