A novel high-nuclearity silver sulfide nanocluster [AgS(SCHF)(dppp)]·4DMI, (hereafter abbreviated as 1⋅4DMI) was synthesised. Solvent-free crystals of 1 displayed a completely reversible narrowing and broadening of the optical band gap that was accompanied by visual thermochromism and piezochromism changeovers, when stimulated by varying temperatures between 113 and 413 K or by changing the pressure from 1 atm to 7.5 GPa.
合成了一种新型的高核硫化银纳米团簇[AgS(SCHF)(dppp)]·4DMI（以下简称为1·4DMI）。当在113至413 K之间改变温度或从1个大气压改变到7.5 GPa的压力刺激时，1的无溶剂晶体显示出完全可逆的光学带隙变窄和变宽，并伴随着视觉热致变色和压致变色转变。
