Comprehensive Investigation of the Photophysical Behavior of Oligopolyfurans
Melo, J. Seixas de; Elisei, Fausto; Gartner, Carlos; Aloisi, Gian Gaetano; Becker, Ralph S.The photophysical properties of (oligo)polyfurans (Fn, where n = 1−5 represents the number of rings) are presented for the first time for 2−4 rings and compared to parallel data for the corresponding (oligo)polythiophenes (Tn). The quantum yields of fluorescence of the polyfurans are consistently considerably greater (5−50-fold), and that of the triplet occupation, considerably smaller (2.5−4) than for the poly...

Becker, Ralph S.; Melo, J. Seixas de; Maçanita, António L.; Elisei, FaustoA large basis set of R-oligothiophenes with two to seven rings (R2-R7), also including thiophene, R1, have been investigated in five solvents regarding absorption, fluorescence and phosphorescence, quantum yields of fluorescence ( F) and triplet formation ( T), lifetimes of fluorescence and the triplet state, quantum yields of singlet oxygen production ( ¢), all rate constants kF, kIC, kISC, and several of the ...
