Highly efficient electrochemiluminescence on microporous MOFs containing zinc secondary building units with a pcu net

摘要

AbstractTwo 3D microporous MOFs, [Zn4(μ4-O)(μ4-pzca)3]n(1) and {[Zn2(pzca)2(4, 4'-bipy)]·2H2O}n(2) (H2pzca=1H-pyrazole-4-carboxylic acid) were synthesized. The X-ray data reveals that the 1 contains [Zn4(μ4-O)(CO2)6] and [Zn4(μ4-O)(N2)6] SBUs, the 2 contains Zn2N6O2SBUs. Furthermore, MOFs 1 and 2 have a same topologypcunet. Interestingly MOF 1 exhibits good ECL (electrochemiluminescence) behavior.Graphical abstractIn this article, we first synthesized two new 3D MOFs based on 1H-pyrazole-carboxylic acid. Interestingly, the title MOFs have the same topology net,pcu
