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

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.
