Poly(p-phenylene phosphaborene): A Modified Poly(p-phenylene vinylene) with π-Conjugated B═P Linkages.

ABSTRACT: While the isoelectronic substitution of selected C═C by B═N units in π-conjugated organic compounds has evolved into a well-established concept to create novel hybrid materials with modified properties, the use of valence isoelectronic B═P units for such purposes has been hardly explored. Herein, we demonstrate substitutional doping of the famous optoelectronic organic polymer poly(p-phenylene vinylene) (PPV) with B═P linking groups for the first time. We report on the successful synthesis of a soluble polymer and a series of monodisperse oligomers of BP-PPV type. Our structural and photophysical investigations, supported by in-depth DFT calculations, evidence effective π-conjugation along their backbone, which is similary pronounced as in their previously reported BN congeners.
