Poly(thienylene vinylene)s (PTVs) are a unique class of low bandgap conjugatedpolymers that have received relatively little attention in organic electronic applications due to the limitations in conventional synthetic methodologies that are not capable to produce PTV structures beyond the rudimentary forms. We report here facile synthetic methods, combining acyclic diene metathesis (ADMET) and postpolymerization

successes from symmetric small molecules, asymmetric ones have recently emerged as an alternative choice. In this paper, we present the synthesis and photovoltaic properties of four asymmetric small molecule donors. The benzo[1,2-b:4,5-b′]dithiophene (BDT) end in the asymmetric push–pull CNR–DPP–BDT (CNR = octyl-2-cyano-3-(thiophen-2-yl)acrylate, DPP = diketopyrrolopyrrole) was tailored from hydrogen
