Two-dimension (2D)-conjugation and donor−acceptor (D−A) copolymerization have been proven to be two successful strategies in the molecular design of high performance donor materials. Among the 2D-conjugated polymers, the copolymers based on thiophene unit with conjugated D−A side chain demonstrate the advantages of enhanced absorbance and lowlying HOMO energy level. In this work, we present the synthesis and detailed characterization of 2D-conjugated side-chain D−A copolymers which are prepared from the combination of the DPP unit with thiophene derivatives via Stille coupling reaction. The main intention of designing this polymer is to study the effect of energy transfer on optical, electrochemical and device performance properties of the polymers by rational molecular design. |
