A microporous metal鈥搊rganic framework (FJU-12), {[Cd₁₂(Trz)₈(DMF)₂(H₂O)₄](BDC)₉}路2(Me₂NH₂)路4DMF路16H₂O (Trz = 1,2,4-triazole, BDC = terephthalic acid, DMF = N,N-dimethylformamide), was rationally constructed using unprecedented lantern-like 1,2,4-triazole-based dodecanuclear metal coordination cages as supermolecular building blocks. After activation, FJU-12a exhibits highly selective adsorption of C₂ compound/CH₄ mixtures and efficient sensing of nitrobenzene (NB). The selectivity (79.7) of C₂H₂/CH₄ is comparable to the most selective Cu-TDPAT (82, TDPAT = 2,4,6-tris(3,5-dicarboxylphenylamino)-1,3,5-triazine).
