three soluble perinone isomers as electron transport materials in p–i–nperovskitesolarcells. The cis-isomer BBIN-2 possesses higher LUMO level and electron mobility than the trans-isomers. The BBIN-2 devices showed the highest power conversion efficiency of 19.36%, demonstrating the potential of perinone dyes in perovskitesolarcells.
pi-Extended thienoacenes that comprise alternatively arranged anthracene and thieno[3,2-b]thiophene moieties and have 8 or 13 aromatic rings were synthesized. The delocalization of their HOMO and LUMO orbitals is over the entire molecules, and low-lying HOMO levels endow them good stability. (C) 2014 Elsevier Ltd. All rights reserved.
