Progelator complex Zn-TRPA-2 undergoes Cl(-) triggered gelation to afford ZTP2G, while Zn-TRPA-2 capped Au-NPs under similar conditions gave another gel GNZTP2G which also represents a rare nano-composite metallogel. When Zn-TRPA-2 was triggered by Cl(-) and NO3(-) simultaneously, crystals of demetalated species NA-TRPA-2 grew inside the ZTP2G matrix. Interestingly, GNZTP2G exhibits superior viscoelastic properties over ZTP2G.
Progelator复合物Zn - TRPA - 2在Cl(-)触发下发生凝胶化形成ZTP2G，而在类似条件下Zn - TRPA - 2包覆的金纳米颗粒形成另一种凝胶GNZTP2G，它也是一种罕见的纳米复合金属凝胶。当Zn - TRPA - 2同时被Cl(-)和NO3(-)触发时，脱金属物种NA - TRPA - 2的晶体在ZTP2G基质内部生长。有趣的是，GNZTP2G比ZTP2G表现出更优异的粘弹性。
