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

Tri- and pentanuclear, kinetically stable SBUs were exploited for the preparation of the novel MOFs [Zn3(BTEB)2(DMF)2] and (Me2NH2)[Zn5(BTEB)3(μ3-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.
