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.

The sense of smell allows organisms to detect a large number of volatile substances in the environment. Olfaction is an essential sense for the survival of any organism, especially to determine the edibility of the food or to detect potential dangers. This sense also plays a major role in the social behavior of many species, such as partner choice or group recognition. In humans, olfaction is involved in the acceptability of food as well as in the recognition of the environment. The aroma characteristics of molecules can evaluate by computational methods for its great advantages. The quantitative structure activity/propriety relationship QSAR/QSPR models are theoretical methods used to investigate the relations between chemical structure (molecular descriptors) of a set of compounds and their biological activity or chemical property. Therefore, these methods make it possible to evaluate, interpret and predict the aroma characteristic of volatile compounds considered as bioactive molecules able to activate biological targets (olfactory receptors).
