Strategies to Incorporate Mesoporosity - Mesoporous Organic-Inorganic Non-Siliceous Hybrid Materials - page 54

mesoporous MOFs constructed by metal disulfonate [La(1,5-nds)1.5(H 2 O) 5 ] n
and [Cu(1,5-nds)(H 2 O) 4 ] n were successfully prepared, named as MMOF-2 and
MMOF-3, respectively. Mesoporous MOFs consisting of layered Sr[C 2 H 4 (SO 3 ) 2 ]
were obtained using ethanedisulfonic acid, named as MMOF-4. It is expected
that the crystalline mesoporous frameworks can be constructed from many other
types of easily crystallized materials by controlled release of metal ions, leading
to enhanced functionality. This soft-templating assembly route should be generally
transferable to other mesoporous MOFs with an appropriate choice of functional
groups.
The controlled synthesis of mesoporous non-siliceous organic-inorganic
hybrids includes the adjustment of pore sizes, mesophase symmetry, crystallin-
ity of the pore walls, and micro-/macroscopic morphologies. Various mature and
burgeoning technologies can be employed to attain the desired targets. However,
the achievement of well-structured mesophases and a high crystalline degree at the
same time are still a contradiction. The effective control of the mesophase is still
challenging, but especially significant in the areas of adsorption, separation, and
catalysis.
