Abstract
A three-dimensional pyrene assembly on a tetraphenylethane skeleton enhanced the fluorescence quantum yield compared to the yield obtained when using monomeric species, without changing the shape of the emission spectrum. The unique spacing of the pyrene units may prevent intramolecular fluorescence quenching or non-radiative decay.
摘要
四苯乙烯骨架上的三维苝组装体与使用单体时获得的荧光量子产率相比有所提高，而发射光谱的形状没有改变。苝单元的独特间隔可能防止了分子内荧光猝灭或非辐射衰减。
