英语翻译
Reversible construction of a nanoporous framework from a
nonporous framework has been found in the zinc(II) coordination
polymer with 4,4¢-oxybis(benzoate) (oba).[Zn2(oba)2(dmf)2]â2DMF
(1),which has 1 nm scale channels,transforms to the nonporous
coordination polymer [Zn(oba)(H2O)] (2) with the loss of the open
framework.Compound 2 on treatment with DMF reversibly yields
nanoporous compound 1.
Coordination polymers with porous frameworks have
attracted attention as a new class of porous materials because
these materials have shown new porous functions that are
not found in inorganic porous materials such as zeolites and
graphite.1-7 For example,heterogeneous catalysis,2 anion
exchange,3 and molecular adsorption and storage4 have been
reported to date.Their frameworks are unstable and flexible
in many cases,and various new functions based on the
dynamic porous frameworks have been created.5-8 One of
the recent interests in this field is the reversible transformation
between a nanoporous framework and a nonporousframework accompanying the release and readsorption of
guest molecules responding to external stimuli.5,6,8 For
example,Pan et al.have reported a recyclable nanoporous
coordination framework that changes to a nonporous framework
by addition of water with loss of a pillar framework
ligand,4,4¢-bipyridine (4,4¢-bpy).6 This reaction enforces the
release of the included guest molecules.Moreover,treatment
of the resulting nonporous framework with 4,4¢-bpy in DMF
at 150 °C reproduces the original porous framework.
We have focused on the synthesis of new coordination
networks with chalcogen atoms in the organic backbone.8a,9
Recently,we selected 4,4¢-oxybis(benzoate) (oba; Scheme
1) as a bridging ligand for creation of new coordination
frameworks,and we have succeeded in the synthesis of the
two new coordination polymers:nanoporous coordination
polymer,[Zn2(oba)2(dmf)2]â2DMF (1) and [Zn(oba)(H2O)](2).Here,we report the synthesis,structures,and the unique
dynamic structural changes that reversibly transform their
frameworks,depending on the solvents,with loss and
recreation of the porous framework
