Abstract: The first oxidation (reduction) potentials have been measured by cyclic voltammetry for twenty-five different triphenylene based discotic liquid crystals and related systems. The measured potentials correlate reasonably well with values calculated at the PM3 level and can be understood in terms of substituent effects. There is a substantial difference between the oxidation potentials of the components in mixed CPI systems; a surprising finding in view of their high hole mobilities. For 2,3,7,8,12,13-hexakis(2-(20-methoxyethoxy)- ethoxy) tricycloquinazoline both CV and NMR show that there is aggregation in acetonitrile solutions.
