The fluorescence properties of (3)–(6) in solvents of varying polarity have been examined and the conclusion reached that in non-polar solvents they exhibit fluorescence (low quantum yield) from an intramolecular ternary complex. In polar solvents very little fluorescence is observable. Although each compound exhibits extensive intramolecular fluorescence quenching, the quantum yield of localised triplet
研究了(3)–(6)在不同极性溶剂中的荧光性质,得出的结论是,在非极性溶剂中,它们显示出分子内三元络合物的荧光(低量子产率)。在极性溶剂中,几乎看不到荧光。尽管每种化合物均表现出广泛的分子内荧光猝灭,但非极性溶剂中局部三重萘的量子产率仍然相对较高,这表明在非松弛的激基复合物中发生了系统间交叉。
