There is provided p-type organic polymers of general formula I. The polymers may be useful as semi-conducting material. Thus, thin films and devices comprising such polymers are also provided.
polymer solarcells (PSCs) using phenyl-C71-butyric acid methyl ester (PC71BM) as the electron acceptor material were fabricated. The sidechains on the polymer backbone have a strong impact on the film morphology of the polymer:PC71BM blends. A phase separation with a relatively larger domain size was found for the polymers with longer sidechains, while those with relatively shorter alkyl chains could
