Abstract
Six novel pyrromethene-BF2 complexes, of which five compounds have not been reported, were synthesized and characterized. Their relationships between structure and photophysical behavior were studied with the aid of fluorescence and triplet state absorption spectra. The results indicate that, compared to 8-alkylpyrromethene-BF2 complexes, the compounds containing 8-aryl exhibit high fluorescence quantum yield and rather low triplet state absorption.
