摘要: 1988年Pavlopoulos等人发现1,3,5,7-四甲基吡咯亚甲基BF2化合物是一个性能优良的激光染料[1].它的荧光量子效率高,激光效率比香豆素540A高10%,并具有低的三重态吸收和高的光化学稳定性.因此,在染料激光、生物荧光探针、光动力疗法等方面都有潜在的应用背景[2~4].

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.
