Researchers in Czech Republic have experimentally confirmed the correctness of a decades-old theory that assumed a non-uniform distribution of electron density in aromatic molecules, a phenomenon that significantly affects the physicochemical properties of molecules and their interactions. They presented the resolution of the Ï€-hole on a single molecule which supports the theoretical prediction of its existence. Experimental measurements supported by theoretical calculations showed the importance of Ï€-holes in the process of adsorption of molecules on solid-state surfaces. According to the researchers better knowledge of the distribution of the electron charge will help the scientific community to understand many chemical and biological processes in the first place. On a practical level, it will translate into the ability to build new supramolecules and subsequently into the development of advanced nanomaterials with improved properties… read more.
