Abstract

See full text

In one embodiment of the present disclosure, a series of conjugated polymers used, among other things, as polymer solar cell or polymer photovoltaic device active layer materials, is provided. In one embodiment, the conjugated polymers have the general structure and formula shown in (I), wherein: R1 and R2 are independently selected from proton, halogens, alkyls, aryls and substituted aryls; Ar is selected from the group consisting of monocyclic, bicyclic and polycyclic arylene, or monocyclic, bicyclic and polycyclic heteroarylene. In another embodiment, the conjugated photovoltaic polymers are comprised of repeated units having the general structure of formula (II), wherein, R1, R2, R3, R4, R5, and R6 are independently selected from proton, alkyls, halogens, aryls, substituted aryls, and other kinds of substituents. Synthesis methods of several polymers of the present disclosure are provided, and absorption spectra and electrochemical cyclic voltammetry data of some polymers, and also the photovoltaic properties of the polymers in this present disclosure are also provided.
