Herein we present a synthesis of an S-shaped double helicene with fused imide moieties, achieving a contorted aromatic diimide () with good fluorescence properties in both solution and the solid state. demonstrates distinct mechanofluorochromism from yellow to green emission under grinding of its crystalline powder.
在此,我们展示了一种带有稠合酰亚胺部分的S形双螺旋烯的合成方法,得到了一种扭曲的芳香二酰亚胺(),其在溶液和固态中均具有良好的荧光特性。在研磨其结晶粉末时,表现出从黄色到绿色发射的明显机械荧光变色现象。
