Abstract: Abstract A novel, star‐shaped electron acceptor, DMTPA‐PDI3, derived from a planar dimethylmethylene‐bridged triphenylamine core with three acetylene‐linked perylene diimide (PDI) units is developed as a nonfullerene acceptor for organic solar cells (OSCs). DMTPA‐PDI3 manifests significantly… read more here.

DOI: 10.1002/ajoc.202500264
Abstract: We have designed and synthesized a highly electron‐rich compound, an oxygen‐bridged triphenylamine incorporating methylthio groups. The radical cation and dication salts were successfully obtained by oxidation reactions of this compound as isolable solids. X‐ray crystallographic… read more here.
