AbstractThe solid charge-transfer (CT) molecular complexes formed in the reaction of the electron donor 1,4,8,11-tetraazacyclotetradecane (TACTD) with the π-electron acceptors 2,4,6-tetrafluoro-1,4-benzoquinone (TFQ), 2,3-dichloro-5,6-dicyano-1,4-benzoquinone (DDQ) and 2,4,4,6-tetrabromo-2,5-cyclohexadienone (TBCHD) have been investigated spectrophotometrically in chloroform at 25 °C. These were characterized through electronic and infrared spectra as well as elemental and thermal analysis. The obtained results showed that the formed solid CT-complexes have the formulas [(TACTD)(TFQ)2] and [(TACTD)(DDQ)2] and [(TACTD)(TBCHD)2] in full agreement with the known reaction stoichiometry in solution as well as the elemental measurements. The formation constant kCT, molar extinction coefficient εCT, free energy change ΔG0, CT energy ECT and the ionization potential Ip have been calculated for these CT-complexes.
