A new thermostable Sr(II) compound, formulated as [Sr(bdc)(H 2 O)(DMF)] n ⋅ x (solvent) ( 1 , H 2 bdc=terephthalic acid, DMF=N,N’‐dimethylformamide), has been synthesized from the solvothermal reaction of Sr(NO 3 ) 2 and H 2 bdc. The X‐ray structural analysis revealed that compound 1 features a 3D framework based on 1D Sr(II)‐carboxylate chains, and the coordinated and free solvent molecules filled in the 1D channels of 1 , which can be easily removed from the 3D framework via heat treatment activation. The obtained solvent‐free samples 1 a not only shows high adsorption capacities of C 2 H 2 and CO 2 at 298 K, moderate adsorption selectivity for C 2 H 2 /CH 4 , CO 2 /CH 4 , but also can be used as a luminescent probe for the detection of nitroaromatic explosives.
