Περίληψη:
We report herein a new alkaline earth metal ion organic framework
[Mg-2(NH2BDC)(2)(HNO3)]center dot 9H(2)O (AEMOF-7), which shows a 3-D
microporous structure with several unusual features, such as the rare
trigonal prismatic coordination geometry of one of the
crystallographically unique Mg-2(+) centers and the existence of a
bridging HNO3 ligand. The H+ ions of the HNO3 ligand are dissociable as
demonstrated via proton conductivity measurements. AEMOF-7 displays
relatively high selectivity for CO2 vs. CH4 and negligible N-2 uptake.
Interestingly, this compound was found to be capable of
single-crystal-to-single-crystal (SCSC) exchange of Mg2+ by Cu2+ ions,
which was observed for the first time in a MOF material. AEMOF-7 is also
luminescent and its photophysical properties were investigated via solid
state UV-Vis, steady-state and time-resolved luminescence studies.
