Abstract: Two pyrromethene-BF2 complexes are synthesized. Their structures have been comfirmed by IR spectra, 1H NMR spectra, mass spectra and elementary analysis. Sol-gel method was used to dope these dyes in organic modified silicate (Ormosil). Their UV-vis spectra, fluorescence spectra and photostability have also been tested.

Key words: pyrromethene-BF2 complex, fluorescence dye, organic modified silicate(Ormosil), fluorescence sprctra, absorption spectra
