Di-n-alkyl substituted polyfluorenes with alkyl chain lengths of 6, 7, 8, 9, and 10 carbon atoms (PF6, PF7, PF8, PF9, and PF10) are studied in dilute solution in MCH using optical spectroscopy. Beta-phase is formed upon cooling in solutions (∼ 7 µg m... Read More about The Influence of Alkyl-Chain Length on Beta-Phase Formation in Polyfluorenes..

The triplet yield and intersystem crossing rate of a set of conjugated oligomers and polymers that, in polar solvents, form a charge-transfer state with a twisted conformation has been investigated. It was observed that in these dibenzothiophene-fluo... Read More about Enhanced triplet formation by twisted intramolecular charge-transfer excited states in conjugated oligomers and polymers..
