A novel "N-π-N" type oligomeric acceptor of 2BTP-2F-T, constructed by two small non-fullerene acceptor (NFA) units linked with a thiophene π bridge is reported. The 2BTP-2F-T not only combines the advantages of small NFA and polymeric acceptors (PYF-T-o) with similar units but also exhibits superior characteristics of high absorption coefficient and high electron moblity(µ
