to N-heteroaromatics, such as pyridine, pyrimidine, and 2-methylpyrazine. The remarkable colour changes occur due the ligand exchange reaction between the solid and gas. Such ligand exchange reactions would be applicable to various vapours with coordination ability and be useful for the sensing of such volatile organic compounds as well as a new convenient methodology for the preparation of luminescent

甲基吡啶),一种高度发蓝光的单核
铜(I)配合物,显示出可逆的发射颜色变化,范围从蓝绿色通过蒸气暴露于N-杂芳族化合物(例如
吡啶,
嘧啶和
2-甲基吡嗪)而变成红色。显着的颜色变化是由于固体和气体之间的
配体交换反应而发生的。这样的
配体交换反应将适用于具有配位能力的各种蒸气,并且对于感测这种挥发性有机化合物以及用于制备发光络合物的新的方便方法学是有用的。
