合成了二苯并-1，4-磷杂硼烷，并用X-射线单晶分析对其结构进行了表征。磷杂硼化合物具有分子内电荷从磷原子转移到硼原子的紫外/可见光吸收。根据磷原子上取代基的不同，磷杂硼化合物表现出不同的荧光性质。该磷硼烷易于衍生为P-硫化物、P-亚硒酸盐和磷酸盐。该磷酸盐及其P-衍生物与氟离子形成了络合物。络合生成常数随其LUMO能级的降低而增大。
Dibenzo-1,4-phosphaborins were synthesized and characterized by X-ray crystallographic analysis. The phosphaborins exhibited UV/vis absorption derived from intramolecular charge transfer from the phosphorus atom to the boron atom. The phosphaborins showed different fluorescent properties depending on the substituents on the phosphorus atom. The phosphaborin was easily derivatized to P-sulfide, P-selenide and phosphonium salt. The phosphaborin and its P-derivatives formed complexes with fluoride ion. The complex formation constants were shown to increase in accordance with the decrease in their LUMO energy levels.
