Synthesis of N, O π-conjugated boron complexes and the reactivity of Suzuki cross-coupling

π-Conjugated boron complexes have been considered as excellent fluorescent dye system and utilized in various fields, such as organic electronics, photonics, nanoemitters and dyestuff industry. In this paper, we developed a fluoroboron coordination by employing in situ generated BF3·H2O as fluoroboron souce and afforded a series of novel species of N,O π-conjugated boron complexes. Moreover, we achieved the Suzuki cross-coupling reaction of iodo-substituted complex with different boronic acids to further expand the structural diversity of N,O π-conjugated fluoroboron complexes.
