- Abstract
An unprecedented poly(thiophene iminoborane)—a boron–nitrogen analogue of the well‐established conjugated organic polymer poly(thiophene vinylene)—is presented. The polymer synthesis is achieved by selective Si/B exchange polycondensation of a 2,5‐diborylthiophene with a 2,5‐diaminothiophene derivative. For the latter, a facile synthetic strategy is devised, which makes this versatile, strongly electron‐releasing building block easily accessible. The novel polymer and a series of monodisperse thiophene iminoborane oligomers reveal systematic bathochromic shifts in their absorption with increasing chain length, and thus extended π‐conjugation over the BN units along the backbone, which is further supported by TD‐DFT calculations.
