Synthesis and Characterization of Four Novel Supramolecular Compounds Based on Metal Zinc and Cadmium

Abstract: Four zinc(II) or cadmium(II) supramolecular compounds, namely, [Zn(ox)(Him)]n (1), [Zn(bta)2]n (2), [Zn(H2O)4(na)2]n (3), and [Cd2(ox)(OH)2]n (4) (ox = oxalate anion, Him = imidazole, bta = benzotriazole anion, and na = nicotinic anion), have been synthesized. Among them, 1 is constructed to be a 3-D supramolecular framework by covalent and noncovalent interactions, 2 containing two bta coordination modes displays a 2-D layer structure linked by covalent bonds, the 3-D network of 3 is mainly constructed by strong hydrogen bonds, while 4 exhibits a 3-D framework with 1-D channels only constructed by covalent interactions. The different metal centers and ligand dimensions result in the different structures although they were obtained from similar reaction systems. All of these compounds display strong fluorescence emissions in the blue region, which may be assigned to charge transfer between metal and ligand (for 1, 3, and 4) and the π → π* transition of bta (for 2).

Syntheses, characterization and optical properties of some copper(I) halides with 1,10-phenanthroline ligand

Abstract: The hydrothermal reactions of CuX2 or CuX with phen (1,10-phenanthroline) have resulted in the syntheses of eight compounds 1–8. In these, 1∶1 adducts of CuX/phen are reported: ionic [Cu(phen)2][CuX2] (X=Cl 1, Br 2) and dimer [Cu2I2(phen)] 3; the trinuclear clusters [Cu3X3(phen)2] (X=Br 5, I 7) were first prepared and the structures can be best described as 1∶1 adducts of dimers and CuX; the chain compounds 6 and 8 belong to the same series with the formula [CuX2L] (L=organic ligand), but the chain arrangement is different; the structure of 4 is yet being refined. Compounds 1–8 have a high thermal stability. The third-order nonlinear optical properties of compounds 5, 6 and 8 were investigated and all exhibit a reverse saturable absorption (α2>0) and self-defocusing performance (n2<0).

Insights into mucopolysaccharidosis I from the structure and action of α- L -iduronidase

Abstract: Mucopolysaccharidosis type I (MPS I), caused by mutations in the gene encoding α-L-iduronidase (IDUA), is one of approximately 70 genetic disorders collectively known as the lysosomal storage diseases. To gain insight into the basis for MPS I, we crystallized human IDUA produced in an Arabidopsis thaliana cgl mutant. IDUA consists of a TIM barrel domain containing the catalytic site, a β-sandwich domain and a fibronectin-like domain. Structures of IDUA bound to iduronate analogs illustrate the Michaelis complex and reveal a (2,5)B conformation in the glycosyl-enzyme intermediate, which suggest a retaining double displacement reaction involving the nucleophilic Glu299 and the general acid/base Glu182. Unexpectedly, the N-glycan attached to Asn372 interacts with iduronate analogs in the active site and is required for enzymatic activity. Finally, these IDUA structures and biochemical analysis of the disease-relevant P533R mutation have enabled us to correlate the effects of mutations in IDUA to clinical phenotypes.

Luminescent Metal–Organic Frameworks

Abstract: Metal–organic frameworks (MOFs) display a wide range of luminescent behaviors resulting from the multifaceted nature of their structure. In this critical review we discuss the origins of MOF luminosity, which include the linker, the coordinated metal ions, antenna effects, excimer and exciplex formation, and guest molecules. The literature describing these effects is comprehensively surveyed, including a categorization of each report according to the type of luminescence observed. Finally, we discuss potential applications of luminescent MOFs. This review will be of interest to researchers and synthetic chemists attempting to design luminescent MOFs, and those engaged in the extension of MOFs to applications such as chemical, biological, and radiation detection, medical imaging, and electro-optical devices (141 references).

Molecular self-assembly and nanochemistry: A chemical strategy for the synthesis of nanostructures

Abstract: Molecular self-assembly is the spontaneous association of molecules under equilibrium conditions into stable, structurally well-defined aggregates joined by noncovalent bonds. Molecular self-assembly is ubiquitous in biological systems and underlies the formation of a wide variety of complex biological structures. Understanding self-assembly and the associated noncovalent interactions that connect complementary interacting molecular surfaces in biological aggregates is a central concern in structural biochemistry. Self-assembly is also emerging as a new strategy in chemical synthesis, with the potential of generating nonbiological structures with dimensions of 1 to 10(2) nanometers (with molecular weights of 10(4) to 10(10) daltons). Structures in the upper part of this range of sizes are presently inaccessible through chemical synthesis, and the ability to prepare them would open a route to structures comparable in size (and perhaps complementary in function) to those that can be prepared by microlithography and other techniques of microfabrication.

Old materials with new tricks: multifunctional open-framework materials.

Abstract: The literature on open-framework materials has shown numerous examples of porous solids with additional structural, chemical, or physical properties. These materials show promise for applications ranging from sensing, catalysis and separation to multifunctional materials. This critical review provides an up-to-date survey to this new generation of multifunctional open-framework solids. For this, a detailed revision of the different examples so far reported will be presented, classified into five different sections: magnetic, chiral, conducting, optical, and labile open-frameworks for sensing applications.
