The mobility of charge carriers in all four phases of the columnar discotic material hexakis(hexylthio)triphenylene: Combined TOF and PR-TRMC results



Peripherally alkyl-substituted aromatic molecules are of interest because they are predicted to promote the rapid vectorial conduction of electronic charge. It is shown—using the example of HHTT, see Figure—that the results obtained by flash-photolysis time-of-flight conductivity and pulse-radiolysis time-resolved microwave conductivity measurements are complementary, allowing the charge-carrier mobility to be determined in all four phases of HHTT.
