文摘Three novel 8-alkyl pyrromethene-BF2 complexes have been synthesized. Their structures were confirmed by IR, MS, 1H NMR and elemental analysis. Their spectral behavior have been discussed in terms of UV-Vis and fluorescence spectral results, which indicate compound 4bhas a extremely high fluorescence quantum yield.
