“…[ 25 ] Therefore, adjusting the growth rates of different crystal facets should be applicable for the growth of low-dimensional MOFs, e.g., using growth-blocking agents to inhibit the crystal growth in certain directions. [ 26,27 ] As one of the most important MOFs, HKUST-1 (i.e., Cu 3 (BTC) 2 (H 2 O) 3 , where the parent molecule of BTC 3− linker is H 3 BTC (1,3,5-benzenetricarboxylic acid, see Scheme 1 )), has been widely studied since it was fi rst reported in 1999. [ 28 ] In this MOF, all three carboxyl groups in H 3 BTC molecule (through deprotonation) are coordinated with Cu 2+ ions.…”

3268 wileyonlinelibrary.com inorganic nodes in MOFs can be intrinsic active sites for catalysis, e.g., copperbased MOFs have been demonstrated as an excellent solid Lewis acid catalyst for a few reactions; [ 4,7 ] (ii) extrinsic functional species (e.g., nanoparticles) can be introduced to MOFs structure, either on the external surfaces or inside the bulks or shells of MOFs. Various catalytic nanoparticles have been successfully incorporated into different MOFs matrices, including Au, Ag, Pt, Cu, or their combination etc.; [8][9][10] and (iii) MOFs also serve as solid precursors for metal or metaloxide catalysts due to their high metal density within the frameworks and easy transformation. Many porous transition metal oxides, such as CuO, Cu 2 O, Mn 2 O 3 , Mn 3 O 4 , Co 3 O 4 , and ZnO among others, have been derived through thermolysis under controlled atmospheres. [11][12][13][14][15][16] For example, porous CuO hollow architectures with perfect octahedral shape were prepared by annealing HKUST-1 precursor in fl owing air. [ 12 ] Moreover, zeolitic imidazolate framework-67 (ZIF-67) was used to design and generate Co 3 O 4 or structurally more complex Co 3 O 4 /NiCo 2 O 4 . [ 13,14 ] Although increasing research attention has been paid to the catalytic applications of MOFs, to our knowledge, shapes of the studied MOFs are mostly followed in 3D isotropic polyhedrons (i.e., high symmetric MOF crystals with sizes greater than 100 nm), and the catalytic systems derived from MOFs with anisotropic shapes such as nanofi bers or nanosheets with a dimension(s) less than 10 nm have seldom been explored.Similar to many inorganic nanomaterials, tailoring of size and shape is essential to customize MOFs for specifi c applications according to the principle of "structure dictates function." [ 17 ] Although a fi ne control over the size and size-distribution of MOFs has been realized, e.g., in the range of 100 nm to several micrometers, [ 18 ] fashioning MOFs into desired shapes for specifi c applications remain to be challenging. Nevertheless, several attempts to the architectural control of MOFs shapes have recently appeared in the literature, ranging from 1D, 2D to 3D nanostructures. [ 19,20 ] For example, nanosheets of MOFs as molecular sieving membranes for gas separation have been made in two recent reports, [ 21,22 ] which achieved much higher separation selectivity than MOFs in other

“…Oh et al [282] reported an inverse relationship between the amount of pyridine in the reaction and the length of nicely hexagonally shaped particles of [In(OH)(BDC)] n CPs, so that rods typically 16 µm long could decrease one order of magnitude, when either the capping agent was absent or in 25 equivalents, respectively. Interestingly, the dimensions of the hexagonal facet did not change regardless the concentration of pyridine, that is, the blocking effect affected selectively one growth direction.…”

“…Other studies have also reported the inherent difficulties involved in determining the exact molecular structure of CPs. 16,17 Nevertheless, the band at 319 cm -1 in the Raman spectrum corresponds to the formation of Cd-O and Cd-S bonds; this confirms the extended coordination of the O and S atoms of MSA to the Cd(II) ion (Figure 1e). 18 The formation of the Cd thiolate complex indicates the possible conversion of the complex into CdS particles by calcination.…”

Coordination polymers (CPs) 1-3 have attracted considerable attention because of their potential applications in gas storage, [4][5][6] catalysis, 7 ion exchange, 8 separation, 9 biomedicine, 10,11 etc. For use in the abovementioned applications, the structure and morphology of these CPs have been controlled by judicious choice of metals, ligands, and reaction conditions. Recently, Oh and coworkers have reported that CPs can be successfully converted into metal oxides by calcination without causing any significant change in their morphology. 12,13 This strategy offers great opportunities to CPs chemistry that various metal oxides can be formed as morphologies of CPs dictate. The CPs synthesized thus far mainly comprise transition metal ions and organic ligands having more than two carboxylate functional groups. The synthesized CPs are calcined to form metal oxides, while maintaining the shape of the particles of the former. Many of the important compound semiconductors are metal chalcogenides formed between a metal and sulfur. Yamamoto's group has reported that (alkylthiolato)metal complexes can be pyrolyzed to form metal sulfides.14 The same strategy can be applied to the preparation of metal sulfide nanostructures and microstructures. Metal sulfides are synthesized as follows. Metal ions are allowed to react with ligands containing sulfur sources, such as organothiols, to form metal sulfide CPs, which are subsequently calcined to obtain metal sulfide nanostructures or microstructures. This is expected to be a novel method for obtaining metal sulfide nanostructures or microstructures via the formation of metal thiolate CPs. Herein, we report the formation of CPs from Cd(II) ions and mercaptosuccinic acid (MSA) in aqueous solution and the calcination of the obtained CPs to form CdS particles without any change in the morphology.
