Introduction of the symmetric conjugated side chain to the conjugated backbone of the polymer was found to improve both the light-harvesting ability of the polymer and its charge carrier mobility, apparently by increasing the packing between the polymer chains.

Thiophene Derivatives

Two novel conjugated polymers (P1 and P2), consisting of 2,5-dioctyloxy-1,4- phenylenevinylene and terthiophene derivative based on 3,4-ethylenedioxythiophene, named TTh-Oxa, with oxadiazole side chains, have been synthesized via the Witting–Horner reaction. Another poly(p-phenylene vinylene) (PPV) derivative P3 was also prepared for comparison. The introduction of TTh-Oxa unit in polymer benefits to widening and red shifting the absorption spectra of PPV derivatives. Photovoltaic cells were fabricated with the as-synthesized polymers as the donors and [6,6]-phenyl-C61-butyric acid methyl ester (PCBM) as the acceptor in a 1:4 weight ratio. The device based on P1 showed a maximum power conversion efficiency of 0.64 % under simulated AM 1.5 G solar irradiation (100 mW/cm2).
