本文提出了一种具有融合亚胺基团的s形双螺旋烯的合成方法，得到了在溶液和固体状态下都具有良好荧光性能的扭曲芳香二亚胺（DHDI）。在其结晶粉末的研磨下，dhdi显示出从黄色到绿色的明显机械荧光。
Herein we present a synthesis of an S-shaped double helicene with fused imide moieties, achieving a contorted aromatic diimide (DHDI) with good fluorescence properties in both solution and the solid state.DHDIdemonstrates distinct mechanofluorochromism from yellow to green emission under grinding of its crystalline powder.
