diimide, displaying fluorescence (FL) and circularly polarised luminescence (CPL) over nearly the entire visible spectrum dependent on solvent polarity. The synthesised molecule exhibits an unusual solvent polarity dependence of FL quantum yield and nonradiative rate constant, as well as remarkable gabs and glum values along with high configurational stability.
在本次通讯中,我们描述了一种名为 9,10-二甲氧基-[7]螺烯二酰亚胺的螺旋手性推拉分子,根据溶剂极性,在几乎整个可见光谱上显示荧光 (FL) 和圆偏振发光 (CPL)。合成的分子表现出 FL 量子产率和非辐射速率常数的不寻常的溶剂极性依赖性,以及显着的gabs和glum值以及高构型稳定性。
