摘要

Abstract A series of novel soluble donor-acceptor low-bandgap-conjugated polymers consisting of different oligothiophene (OTh) coupled to electron-accepting moiety 2-pyran-4- ylidenemalononitrile (PM)-based unit were synthesized by Stille or Suzuki coupling polymerization. The combination of electron-accepting PM building block with varied OTh n (the number of thiophene unit increases from 3 to 5) results in enhanced π–π stacking in ...
