Abstract
The photophysical properties of 2,3,6,7,10,11-hexakis(n-hexylsulfanyl) triphenylene and 2,3,6,7,10,11-hexakis(n-hexylsulfonyl)triphenylene ha ve been investigated by absorption, fluorescence and phosphorescence s pectroscopy and compared with parent triphenylene and 2,3,6,7,10,11-he xakis(n-hexyloxy)triphenylene. It is concluded that alkylsulfanyl subs tituents interact more strongly with the triphenylene core than alkyls ulfonyl and alkyloxy substituents, as revealed by the absorption and e mission spectra as well as by the rate constants for the radiative and non-radiative processes. In terms of photophysical properties, 2,3,6, 7,10,11-hexakis(n-hexylsulfonyl)triphenylene and 2,3,6,7,10,11-hexakis (n-hexyloxy)triphenylene are very much alike. 2,3,6,7,10,11-Hexakis(n- hexylsulfanyl)triphenylene aggregates in cyclohexane at concentrations above ca. 10(-3) M.
