The Studies of Molecular Systems

Abstract

There are only 4 types of chemical bonding, covalent bond, ionic bond, metallic bond and molecular bond (van der Waals force). Hybridizations of each 4 bonding enable to create a diversity of chemical compounds, which number increased to nearly a hundred million now. We can select the needed characteristics from this variety of substances, that why we think chemistry is interesting.
The breakthrough of our discovery of electrical conduction in organic solids issued from the consideration of the characteristics that both polycyclic aromatic compounds and highly electrically-conductive graphite possess many π-electrons in the compounds. We report why and how we were engaged in the study of organic semiconductors and we hope it helps leading to the discovery of new materials.
