Polymerizing the narrow bandgap small-molecule architecture with a conjugated linking unit(or called the polymerized small molecule acceptors(PSMAs))is a promising strategy to design polymer acceptors for efficient all polymer solar cells(all-PSCs).Currently,the fused-ring-based small molecule acceptors(SMAs)are preferred monomers to design efficient PSMAs,leaving the challenge of reducing the materials cost.In this work,we firstly employ nonfused-core SMA with simple synthetic procedures to design PSMAs(namely PBTI-H,PBTI-F and PBTI-Cl)to address this issue.Relative to the fused-ring based counterparts,these three PSMAs exhibit much higher figure-of-merit value.Additionally,a power-conversion efficiency of 8.80%is achieved in the PBTI-Cl-based all-PSC.The results offer an attractive approach to design low-cost PSMAs for efficient all-PSCs. 展开更多
