ZZIT-1 is a two-fold interpenetrating 3D framework structure. The gas/vapor adsorption behavior and luminescence of the complex have been studied. Notably, ZZIT-1 can selectively adsorb CO2 over N2, and MeOH over EtOH, and these adsorption results have been corroborated by theoretical calculations. Most interestingly, ZZIT-1 shows unique selectivity for the detection of acetone through a fluorescence quenching mechanism in the solid state at room temperature.Graphical abstract
