Tricoordinate boron embedded conjugated polymers, so-called p−π* conjugated polymers, have been studied as optoelectronic and sensor materials. p−π* Conjugated polymers usually possess bulky aryl groups that kinetically stabilize the boron centers, and the bulky aryl substituents prohibit intermolecular interactions in the solid state. In this work, we synthesized new p−π* conjugated polymers based on a thiophene-fused thiaborin unit. The thiaborin-based p−π* conjugated polymers exhibited great red shifts in the absorption spectra measured in film state relative to those measured in solution, suggesting strong intermolecular interactions.
