A family of polyaryl 2-(pyridin-2-yl)phenol-based four-coordinate organoboron complexes were prepared in good yields via deconstructive cycloaromatization of indolizines, cyclopropenones, and boric acids. The photoluminescence measurements have revealed that these N,O π-conjugated tetracoordinate boron complexes display bright fluorescence, large Stokes shifts, and good quantum yields (Φlum = 0.15—0.45). In addition, the DFT calculations were carried out to deepen the understanding of the electronic structures and optoelectronic properties of these structurally unprecedented tetracoordinate boron complexes.

聚芳基2-(吡啶-2-基)苯酚基四配位有机硼配合物的合成及光学性质
通过中吲嗪、环丙烯酮和硼酸的解构环芳构化，以良好的产率制备了一类聚芳基 2-(吡啶-2-基) 苯酚基四配位有机硼配合物。光致发光测量表明，这些N,O π -共轭四配位硼配合物显示出明亮的荧光、大的斯托克斯位移和良好的量子产率 ( Φ lum = 0.15-0.45)。此外，还进行了 DFT 计算，以加深对这些结构上前所未有的四配位硼配合物的电子结构和光电特性的理解。
