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.
