The electrical and photoelectrical characteristics of sandwich-type devices based on regioregular head-to-tail poly(3-alkylthiophenes) have been investigated and compared with those obtained with regiorandom polymers. Better performances have been achieved in sandwich-type devices made with regioregular polymers having a short alkyl substituent. A spectroscopic and morphological investigation of the materials have been also done.

Abstract
The electrical and photoelectrical characteristics of sandwich-type devices based on regioregular head-to-tail poly(3-alkylthiophenes) have been investigated and compared with those obtained with regiorandom polymers. Better performances have been achieved in sandwich-type devices made with regioregular polymers having a short alkyl substituent. A spectroscopic and morphological investigation of the materials have been also done.File in questo prodotto:
