Application

1,3,5-Phenyltriboronic acid, tris(pinacol) ester can undergo Suzuki–Miyaura cross-coupling polycondensation reaction with 4,7-dibromobenzo[c][1,2,5]thiadiazole to afford conjugated polybenzothiadiazoles. It may also be used as a crosslinker for synthesizing conjugated microporous polymer (CMP) nanoparticles. This product was previously listed as BML00299.
