An Intensely Luminescent Metal–Organic Framework Based on a Highly Light-Harvesting Dyclo-Metalated Iridium(III) Unit Showing Effective Detection of Explosives

An intense visible yellow-orange emission with long lifetime and enhanced quantum yield has been achieved for a metal–organic framework based on a highly light-harvesting dyclo-metalated iridium­(III) unit, which shows effective detection of nitroaromatic explosives on the ppm scale.
