Molecular-dipole oriented universal growth of conjugated polymers into semiconducting single-crystal thin films.

ABSTRACT: Precise control over crystallinity and morphology of conjugated polymers (CPs) is essential for progressing organic electronics. However, manufacturing single-crystal thin films of CPs presents substantial challenges due to their complex molecular structures, distorted chain conformations, and unbalanced crystallization kinetics. In this work, we demonstrate a universal nanoconfined molecular-dipole orientating strategy to craft high-quality single-crystal thin films for a variety of CPs, spanning from traditional thiophene- and theinothiophene-based homopolymers to diketopyrrolopyrrole- (i.e., p-type) and naphthalene-based (i.e., n-type) donor-acceptor copolymers. Central to this strategy is the synergetic manipulations of molecular dipoles, π-π stackings, and alkyl-alkyl interactions of
