Abstract
The chromic behaviour of a soluble ω-hydroxydecyl 3-substituted polythiophene has been investigated by UV-VIS spectroscopy in different solvent/non-solvent mixtures over a wide range of low temperatures. Some interesting new effects have been observed that is the first case of a reversal of the solvatochromic transformation in substituted polythiopenes and a concentration effect in dilute pure solvent solutions. A molecular approach based on solvent-polymer interactions has been adopted to study the conformational chromic transformation of the polymer. © 2001 Elsevier Science B.V.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
