Dibenzophosphaborin:A Hetero-pi-conjugated Molecule with Fluorescent Properties Based on Intramolecular Charge Transfer between Phosphorus and Boron Atoms

摘要

The first dibenzo-1,4-phosphaborins were synthesized and characterized by X-ray crystailographic 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.
