Colorimetric and luminescent sensing of DMF by crystalline non-porous pyrene-based coordination compounds†
Here, two non-porous coordination compounds, [Co2(trz-pyr)5(NCS)4]·3MeOH (1) and [Fe2(trz-pyr)5(NCS)4]·3MeOH (2), are presented as promising new materials for N,N-dimethylformamide (DMF) sensing. Unlike conventional metal organic-frameworks (MOFs), these non-porous compounds achieve “porous-like” behavior through crystal lattice reorganization upon DMF exposure. Crucially, both compounds demonstrate clear color changes when exposed to DMF vapors: compound 1 shifts from orange to green, and compound 2 changes from orange to dark red. This visual response is further supported by changes in their photoluminescence spectra, with a doubling of emission intensity, and confirmed by PXRD and FTIR data. These findings highlight the potential of these non-porous coordination compounds for developing sensitive and selective DMF sensors with real-time monitoring capabilities.
