Spectral and Photophysical Studies on Cruciform Oligothiophenes in Solution and...
Pina, J.; Melo, J. Seixas de; Burrows, H. D.; Bilge, A.; Farrell, T.; Forster, M.; Scherf, U.The photophysical and spectroscopic properties of a new class of oligothiophene derivatives, designated as cruciform oligomers, have been investigated in solution (room and low temperature) and in the solid state (as thin films in Zeonex matrixes). The study comprises absorption, emission, and triplet−triplet absorption spectra, together with quantitative measurements of quantum yields (fluorescence, intersyste...
Hole formation and transfer in poly[9,9-di(ethylhexyl)fluorene] and an amine en...
Burrows, H. D.; Seixas de Melo, J.; Forster, M.; Güntner, R.; Scherf, U.; Monkman, A. P.; Navaratnam, S.Pulse radiolysis has been used to study the positively charged state of isolated chains of poly[9,9-di(ethylhexyl)fluorene] in chloroform solution. This is found to have an absorption maximum at 560 nm and a weaker band around 420 nm. Intermolecular electron transfer is observed from the aromatic amine tri(p-tolylamine) to this species. With the corresponding polyfluorene derivative end-capped by an arylamine, ...
