摘要:A novel supermolecular building blocks (SBBs) based metal-organic framework (MOF), with formula [Zn _7(TMBHB) _2?2NO _3?5DMF?4CH _3CH _2OH?6H _2O] _n (SDU-1), was constructed from C _3-symmetric trimethyl substituted 3,3′,3″,5,5′,5″-benzene-1,3,5- triylhexabenzoic acid (H _6TMBHB). Notably, the SDU-1 consists of two kinds of rare secondary building units (SBUs), [Zn _2(COO) _3] and [Zn _2(COO) _4], which are linked by TMBHB to form cubic and trisoctahedral SBBs, respectively. TOPOS software analysis of SDU-1 indicates that two alternative simplifications based on different SBBs can produce (3,24)-connected rht or (4,12)-connected ftw topologies. Compared with a recently reported Zn-BHB (H _6BHB = 3,3′,3″,5,5′, 5″-benzene-1,3,5-triylhexabenzoic acid) MOF, the structural dissimilarity between them was caused by the steric hindrance of three methyl groups, which makes three isophthalate units on TMBHB nearly perpendicular to the central phenyl ring, giving TMBHB a nonplanar conformation. The photoluminescence behavior of SDU-1 was also discussed.
