Abstract: An inorganic poly(p-phenylene vinylene) (PPV) analogue with a strictly alternating arrangement of BN units along the chain was prepared by an AB-polymerization process. The polymer and monodisperse oligomers show emission from locally excited (LE) or twisted intramolecular charge transfer (TICT) states, respectively, which can be addressed by various stimuli, giving rise to solvatochromic, thermochromic, and reversible mechanochromic behavior.
