Solution-processable organic conjugated polymers (CPs) have become the preferred materials for flexible organic electronic devices as active semiconducting elements. Recently, research interest in Donor-Acceptor (D-A) conjugated polymers has grown, featuring alternating donor and acceptor moieties with varying electron affinity and a rigid, rod-like molecular structure. Among these, Diketopyrrolopyrrole (DPP)-based D-A copolymers stand out for their robust aggregation, lengthy alkyl chains, excellent thermal stability, and efficient charge carrier transport. In this study, we incorporated Benzo[c]cinnoline (BZC) with electron-withdrawing capabilities into DPP, creating a novel π-conjugated framework known as the DPP-BZC class [1]. In addition to creating advanced solution-processable CPs, it is essential to control the molecular orientation in thin films, given their quasi-one-dimensional nature, to fully unlock their potential for device applications. Using the ribbon-shaped floating film transfer method (FTM), we successfully fabricated oriented thin films of this polymer
