文摘

On the basis of the same reaction starting materials, microporous to mesoporous Mn(II)-tris((4-carboxyl)phenylduryl)amine frameworks (FIR-34 to FIR-36, FIR denotes Fujian Institute of Research) with different interpenetration structures have been obtained by applying different solvents and reaction temperatures. FIR-34 is an 8-fold interpenetrating dia framework constructed from small dinuclear [Mn₂(COO)₄] secondary building units (SBUs), while FIR-35 based on large Mn5 SBUs is a non-interpenetrating framework with (3,8)-connected tfz-d network. Both of them have low porosity. However, the other non-interpenetrating framework (FIR-36) with large mesopores is built by rod-shaped Mn(II)-carboxylate SBUs. Gas sorption measurements for FIR-36 give a Langmuir surface area of 825.3 m²·g^–1 and a H₂ uptake of 134.5 cm³·g^–1 at 77 K and 1 bar.
