Abstract

Intermolecular interactions between methyl viologen (MV) and benzyl viologen (BV) with macrocyclic molecules (1), (2), (3), (4), (5), (6), (7), (8) and Schiff base crown ether (9) are investigated in acetonitrile solution and in the presence of tetrabutylammonium perchlorate (TBAP) as a supporting electrolyte. The formation constants of the charge transfer (CT) complexes between viologens and macromolecules were determined for the first and the second reduction process at room temperature using cyclic voltammetry at 100 mV/s as a scan rate. The redox potential of all complexes (E) was determined and peak to peak separation (PP) and half-wave potential (E½) were measured for these complexes. Complexes were found to have 1:1 macrocyclic molecules to viologens stoichiometry>
