One‐Step Route to Ladder‐Type C–N Linked Conjugated Polymers

Abstract: A one‐step synthetic method is demonstrated to construct ladder‐type conjugated polymers without the resource to post‐cyclization procedures. The ladder‐type C–N linked conjugated polymers (P1 and P2) and model compounds (1 and 2) are achieved in high yields. The obtained model compounds and polymers display desirable solubility in commonly used solvents and high thermal stability, which show a promising application in photoelectric material field.

“…The unique multiple-stranded architecture of the conjugated ladder polymer endows material with a constrained chain conformation that results in good conjugation, carrier mobility, and luminescence intensity, so it has been widely investigated in organic light-emitting diodes and the organic field effect . Despite remarkable advances in the past decade, fully conjugated ladder-type macromolecules still remain a major synthetic challenge …”

“…Our single‐handed ladder polymers were accessed (Scheme 1) with chirality‐assisted synthesis (CAS), [4aa, 5] which provided us with precise control of the helix geometry (diameter and rise). Please see the Supporting Information for detailed synthetic protocols, as well as a model coupling reaction carried out with tert ‐butyloxycarbonyl (Boc)‐protected ends, which was used to establish the coupling chemistry and proceeded in 92 % yield [13] . Notably, a universal chiral building block 3 , constructed from a shape‐persistent 9,10‐dihydro‐9,10‐ethanoanthracene backbone, can be utilized to create helices with different shapes by simply changing the geometry of the bis(boronic ester) linkage.…”

“…Our group have made some attempts. We once successfully constructed ladder-type C-N-linked conjugated polymers via tandem reaction; specifically, we used the Pd-catalyzed Suzuki coupling/Schiff’s base reaction [ 22 ]. The model compounds are achieved in high yields.…”
