Abstract
Two new three-coordinate organoboron compounds tris[<i>p</i>-(2,2‘dipyridylamino) phenylduryl]borane\n(<b>1</b>) and tris[<i>p</i>-(2,2‘dipyridylamino)biphenylduryl]borane (<b>2</b>) have been synthesized in good yields\nby using Pd-catalyzed Suzuki−Miyauya coupling reactions between tri(<i>p</i>-iododuryl)borane and the\ncorresponding boronic acid. Both compounds display bright blue luminescence when irradiated by\nUV light. The emission band of both compounds is highly solvent-dependent, indicating the presence\nof a highly polarized excited state. These new boron compounds are stable under air in solution\nand the solid state, and are capable of binding to metal ions such as Zn(II) via the 2,2‘-dipyridylamino\nchelating sites. The crystal structures of <b>1 </b>and <b>2 </b>have been determined.
