Abstract

The synthesis of new porous materials with desired properties is a challenging task. It becomes especially difficult if you need to combine several metals in one framework to obtain a heterometallic node. The use of presynthesized complexes for obtaining of new heterometallic metal–organic frameworks could be essential to solve the problem of tailored synthesis. In our study we use presynthesized heterometallic pivalate complex [Li2Zn2 (piv)6 (py)2 ] to obtain new MOFs with heterometallic core as a node of the framework. We are managed to obtain four new heterometallic MOFs: [H2N(CH3 )2 ]2 [Li2Zn2(bdc)4 ]·CH3CN·DMF (1), [Li2Zn2 (H2Br2-bdc)(Br2-bdc)3 ]·2DMF (2), [H2N(CH3 )2 ][LiZn2 (ndc)3 ]·CH3CN (3) and [{Li2Zn2 (dmf)(py)2 }{LiZn(dmf)2 }2 (NO2-bdc)6 ]·5DMF (4). Moreover three of them contain starting tetranuclear core {Li2Zn2 } and saves its geometry. We also demonstrate the influence of substituent in terephthalate ring on preservation of tetranuclear core. For compound 1 it was shown that luminescence of the framework could be quenched when nitrobenzene is included in the pores.
