Dou, Chuandong; Long, Xiaojing; Ding, Zicheng; Xie, Zhiyuan; Liu, Jun; Wang, Lixiang published an article in 2016, the title of the article was An Electron-Deficient Building Block Based on the B<-N Unit: An Electron Acceptor for All-Polymer Solar Cells.Name: [2,2′-Bipyridine]-3,3′-diamine And the article contains the following content:
A double B<-N bridged bipyridyl (BNBP) is a novel electron-deficient building block for polymer electron acceptors in all-polymer solar cells. The B<-N bridging units endow BNBP with fixed planar configuration and low-lying LUMO/HOMO energy levels. As a result, the polymer based on BNBP units (P-BNBP-T) exhibits high electron mobility, low-lying LUMO/HOMO energy levels, and strong absorbance in the visible region, which is desirable for polymer electron acceptors. Preliminary all-polymer solar cell (all-PSC) devices with P-BNBP-T as the electron acceptor and PTB7 as the electron donor exhibit a power conversion efficiency (PCE) of 3.38 %, which is among the highest values of all-PSCs with PTB7 as the electron donor. The experimental process involved the reaction of [2,2'-Bipyridine]-3,3'-diamine(cas: 75449-26-2).Name: [2,2′-Bipyridine]-3,3′-diamine
