摘要：
The photoresponse of Schottky-type junctions between aluminium and poly(3-alkylthiophenes) with different length of the alkyl-chain was investigated. Better results were obtained with the junctions based on the polymers with shorter side-chains, though the absorption spectra reveal an increasing conjugation length with the length of the alkyl-chain. The trend of the photoresponse was explained by taking into account the effect of the substituents on the morphology of these materials. (C) 2001 Elsevier Science B.V. All rights reserved.
