Περίληψη:
A new flexible Cd2+ metal organic framework (MOF), denoted as UCY-3,
which is the second example of a MOF with the ligand H3CIP [H3CIP =
5-(4-carboxybenzylideneamino)isophthalic acid], is reported. It shows a
unique (3,3,6)-connected topology and is based on a neutral non-oxo
triangular [Cd-3(COO)(6)] secondary building unit that appears for the
first time in MOFs chemistry. UCY-3 displays significant structural
flexibility, capability for exchange of the guest solvents by various
organic molecules in a single-crystal-to-single-crystal fashion as well
as breathing capacity allowing the incorporation of relatively large
amount of benzene into its pores. Overall this work indicates that MOFs
based on semi-rigid polytopic ligands may adopt unprecedented structural
types and exhibit unexpectedly high absorption capacities for relatively
bulky organic molecules, as a result of their flexibility and breathing
capability.
