title: Dibenzophosphaborin: a hetero-pi-conjugated molecule with fluorescent properties based on intramolecular charge transfer between phosphorus and boron atoms.
abstract: [reaction: see text] The first 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.
