High luminescence from a substituted polythiophene in a solvent with low solubility

Theander, M. ; Svensson, M. ; Ruseckas, A. ; Zigmantas, Donatas LU orcid ; Sundström, Villy LU ; Andersson, M. R. and Inganas, O. (2001) In Chemical Physics Letters 337(4-6). p.277-283
Abstract
Steady-state and rime-resolved photoluminescence (PL) is used to probe different states of order in highly regular poly(3-(2'-methoxy-5'-octylphenyl)thiophene) (POMeOPT). In a good solvent (chloroform) the polymer has a PL yield of 0.33 and in a solvent with low solubility (mixture of chloroform and toluene) a new phase appears with higher PL yield (0.50). The new phase is attributed to micro-crystals formed by the regular part of the polymer which have low solubility in toluene. The crystallites have highly structured and redshifted electronic transitions compared with chains which are dissolved. (C) 2001 Published by Elsevier Science B.V.
