Non‐aggregated boron–fluorine derivatives with photodynamic activity

Abstract

Novel non‐aggregated boron–fluorine derivatives with large Stokes shift were facilely synthesized and characterized. These dyes show moderate absorptive coefficients and intense fluorescence emission, and excellent photo‐stability in solvents and also in solid state. According to X‐ray single‐crystal analysis, non‐covalent intermolecular interactions provide a rigid structure, which inhibits aggregate formation. These non‐aggregated dyes can generate singlet oxygen under light irradiation, which makes them good candidates for photodynamic therapy. Copyright © 2012 John Wiley & Sons, Ltd.
