摘要：

A remarkable change of the absorption spectrum has been observed in poly(3-alkylthiophene) solutions with changing temperature, which is tentatively interpreted in terms of a conformation change of polymer chains such as a rod-coil transition due to the change of the entanglement of alkyl chains with temperature. The emission intensity has been found to decrease remarkably at low temperature due to this transition.
