Abstract
The discovery of a third, non-luminescent crystalline polymorph of [(C6H11NC)2Au]PF6 is reported. Remarkably, crystals of this polymorph are sensitive to mechanical pressure or to exposure to dichloromethane vapor. In both cases, the conversion produces the yellow, green luminescent polymorph of [(C6H11NC)2Au]PF6 and not the colorless, blue luminescent polymorph.
摘要
据报道，[(C6H11NC)2Au]PF6 的第三种非发光结晶多晶型物被发现。值得注意的是，这种多晶型物的晶体对机械压力或暴露于二氯甲烷蒸气敏感。在这两种情况下，转化都会产生黄色、绿色发光的[(C6H11NC)2Au]PF6 多晶型物，而不是无色、蓝色发光的多晶型物。
