Selective sensing of 2,4,6-trinitrophenol and detection of the ultralow temperature based on a dual-functional MOF as a luminescent sensor

• A new 3D luminescent Cd(II) metal-organic framework has been obtained and characterized.
• It exhibits detection of TNP with high selectivity and recyclability.
• It also exhibits quantitative detection of the ultralow temperature.
• It can be applied as the first potential dual-functional luminescent sensing material for TNP and temperature.

A novel 3D Cd(II) MOF, {[Cd(Ccbp−)(4.4′-bpy)·H2O]·(ClO4−)·2H2O} (1), (Ccbp− = 3-carboxy-1-(4-carboxybenzyl)pyridin-1-ium, 4.4′-bpy = 4.4′-bipyridine), has been successfully synthesized and characterized. Complex 1 possesses a 3D 4-fold interpenetrating dia network with a pyridine cation basic skeleton. This Cd-MOF 1 can be applied as the first potential dual-functional luminescent sensing material for high selective and recyclable sensing of 2,4,6-trinitrophenol and quantitatively detecting the ultralow temperature from 10 to 60 K.
