Rate enhancement of the selective oxidation of hexoses was achieved on an ethynylpyridine (EPy)-functionalized Pt/Al2O3 catalyst. Host-guest interaction between the EPy ligand and a hexose sugar reactant produced a complex with induced chirality on the catalyst surface.

Viologens are known as an excellent electron acceptor and a versatile supramolecular building block, the physical property of which can be tuned by varying N-substitution. Herein, we present class unprecedented quinoid-viologen conjugates wherein quinoidal unit is incorporated part extended π-system viologen units through Such molecules show intriguing optical electronic properties inherited fr...

The self-assembly and solid-state semiconducting properties of single crystals of a trisradical tricationic complex composed of the diradical dicationic cyclobis(paraquat-p-phenylene) (CBPQT(2(•+))) ring and methyl viologen radical cation (MV(•+)) are reported. An organic field effect transistor incorporating single crystals of the CBPQT(2(•+))⊂MV(•+) complex was constructed using lithographic ...

Homogeneously doped crystals of charge transfer (CT-) complexes were grown by incorporating aromatic guest donors in host CT-crystals. The host crystals contained 1,2.4,5-tetracyanobenzene (TCNB) as acceptor and deuterated aromatic electron donors. By using such doped crystals CTcomplexes in a well defined configuration may be studied. The triplet states of the guest complexes were used as ESR ...

In this paper, the inclusion complexation between host and guest in cyclodextrin (CD) chemistry is care fully compared with the coordination interaction between central ion (Mx+) and ligands in coordination chemistry. In viewof the importanceof the concept of the coordinationnumber (CN)ofMx+ in coordination compounds, the inclusion number (IN) is first defined to evaluate the nature of inclusio...

The emergence of compute unified device architecture (CUDA), which has relieved application developers from having to understand complex graphics pipelines, has made the graphics processing unit (GPU) useful not only for graphics applications but also for general applications. In this paper, we present a cycle sharing system named GPU grid, which exploits idle GPU cycles to accelerate scientifi...

In this communication, the charge transfer phenomenon from ionic host lattice to nonionic guest molecule was observed by magnetization and Raman spectroscopy measurements for nonionic and ionic clathrate hydrates. The present findings on the magnetic property of nonionic guest molecules in ionic hydrate might provide important information on the unrevealed nature of host-guest interaction in io...

The host-guest interaction of a series of cyclohexyl-appended guests with cucurbit[8]uril (Q[8]) was studied by ¹H NMR spectroscopy, isothermal titration calorimetry (ITC), and X-ray crystallography. The X-ray structure revealed that two cycloalkane moieties can be simultaneously encapsulated in the hydrophobic cavity of the Q[8] host to form a ternary complex for the first time.

Binding studies between the electron accepting host cyclobis(paraquat-p-phenylene) and a series of electron donors in the presence of differently sized counteranions reveal that both the nature and the concentration of the anion have a large impact on the association strength of the resulting host-guest complex.
