Drug complexes: Perspective from Academic Research

A drug complex or charge transfer complex also called as the electron donor acceptor complex or a molecular complex can be defined as an association of two or more molecules, or of different parts of a large molecule, in which a fraction of electronic charge is transferred between the molecular entities. Charge transfer often occurs in inorganic ligand chemistry involving metals.When we charge a piece of plastic, a comb or a pen and position it near small pieces of paper they get attracted towards it. We also observe that; the comb loses its charge after a few moments. Can we guess why this happens? Where does the charge go? We can say the charge gets transferred to our hand and eventually to the ground. But how does this phenomenon occur? In this section, we shall learn about the phenomenon of charge transfer and the methods by which it occurs.
