Abstract

We successfully designed and constructed a novel mircroporous metal organic framework [Y₄(TATB)₂]·(DMF)_3.5·(H₂O) (ZJU-16, H₃TATB = 4,4′,4′′-(1,3,5-triazine-2,4,6-triyl)tribenzoic acid) from two different types of MBBs (molecular building block) [Y₃(μ₃-OH)(COO⁻)₆] and [Y₉(μ₃-OH)₁₄(COO⁻)₁₂] and a tricarboxylic acid organic linker via solvothermal reaction. ZJU-16 exhibited high thermal and chemical stability; it is stable up to 500 °C and also maintains its integrity in neutral (water), basic and acidic aqueous solutions. Due to suitable pore size and high stability, the desolvated ZJU-16a demonstrates moderately high selective separation of C₂H₂/CH₄ and CO₂/CH₄ at room temperature.
