Their optical, electrochemical, and photovoltaic (PV) properties were studied and are reported. Both the copolymers exhibited long-wavelength absorption covering the whole visible spectral region, which is in CEHTP thin films extended up to near infrared region. Low-optical bandgap values, 1.37 and 1.15 eV, were determined for CEHTF and CEHTP, respectively. PV devices with bulk heterojunction made of blends of copolymers and fullerene derivative [6,6]-phenyl-C61-butyric acid methyl ester were prepared and characterized. Effects of intramolecular charge transfer strength and side-chain nature and length on photophysical properties are discussed.
