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.
