A luminescent ionic liquid containing a cationic rhenium tricarbonyl complex was synthesized. UV photoirradiation of this liquid in the presence of an organic solvent vapor caused a color change and luminescence quenching via photochemical ligand exchange, thereby enabling the photocontrol of vapochromism.

发光的含铼离子液体表现出光致气相变色

合成了一种含有阳离子铼三羰基配合物的发光离子液体。在有机溶剂蒸气的存在下对该液体进行紫外光照射，通过光化学配体交换引起颜色变化和发光猝灭，从而实现对蒸气致变色的光控制。
