Extending the family of Zn-based MOFs: synthetic approaches to chiral framework structures and MOFs with large pores and channels.

چکیده
Tri- and pentanuclear, kinetically stable SBUs were exploited for the preparation of the novel MOFs [Zn(3)(BTEB)(2)(DMF)(2)] and (Me(2)NH(2))[Zn(5)(BTEB)(3)(μ(3)-OH)(2)(DMF)(2)]. The applied synthetic approach results in topologies that are stabilised by tritopic benzene-trisethynylbenzoic acid (BTEB) linkers giving rise to chiral frameworks with large pores or channels.

متن کاملAn in situ self-assembly template strategy for the preparation of hierarchical-pore metal-organic frameworks
Metal-organic frameworks (MOFs) have recently emerged as a new type of nanoporous materials with tailorable structures and functions. Usually, MOFs have uniform pores smaller than 2 nm in size, limiting their practical applications in some cases. Although a few approaches have been adopted to prepare MOFs with larger pores, it is still challenging to synthesize hierarchical-pore MOFs (H-MOFs) w...

متن کامل"Click" post-synthetic modification of metal-organic frameworks with chiral functional adduct for heterogeneous asymmetric catalysis.
Two enantiomeric Zn-MOFs, having l- or d-proline chiral functionality, were achieved through in situ click reactions by modifying two opposite chiral adducts within the same pre-assembled achiral MOFs, respectively. Both of them exhibited remarkable catalytic activities in the relative asymmetric aldol reactions, and led to the formation of opposite enantiomorphs. The significant advantage of t...
