Abstract
Safe storage and transportation of H2 is a fundamental requirement for its wide applications in the future. Controllable release of high-purity H2 from a stable storage medium such as CH3OH before use offers an efficient way of achieving this purpose. In our case, Cu nanoclusters uniformly dispersed onto (001) surfaces of TiO2 nanosheets (TiO2/Cu) are selectively prepared by thermal treatment of HKUST-1 loaded TiO2 nanosheets. One of the TiO2/Cu composites, TiO2/Cu_50, exhibits remarkably high activity toward the selective dehydrogenation of CH3OH to HCHO with a H2 evolution rate of 17.8 mmol h-1 per gram of catalyst within a 16-h photocatalytic reaction (quantum efficiency at 365 nm: 16.4%). Theoretical calculations reveal that interactions of Cu nanoclusters with TiO2 could affect their electronic structures, leading to higher adsorption energy of CH3OH at Ti sites and a lower barrier for the dehydrogenation of CH3OH by the synergistic effect of Cu nanoclusters and TiO2, and lower Gibbs free energy for desorption HCHO and H2 as well.

Abstract
Subnanoparticles (SNPs) with ultrasmall particle sizes (<1 nm) have potential to provide catalytic activity that is superior to that of nanoparticles. Size-controlled CunOx (n = 12, 28, and 60) materials supported on zirconia, prepared using a dendritic macromolecular reactor, exhibited increased ionicity of the Cu-O bonds with a decrease in size of the particles, which was suggested on the basis of the peak intensity in the Cu 2p3/2 region. The polarization of the Cu-O bonds in the ultrasmall copper oxides provides size-dependent catalytic activity in aerobic oxidation of the CH3 group bonded with aromatic rings. The smallest Cu12Ox materials achieved an excellent large turnover number (TON = 40 206) without any significant deactivation.

Abstract
Two triazine-based dendrimers were successfully prepared in 60-75% yields. These newly prepared dendrimers 2a and 2b containing the -NMe(CH2)2NMe- and the -NMe(CH2)4NMe- linkers between two G3 dendrons, respectively, exhibit columnar phases during the thermal process. However, the corresponding dendrimers 1a and 1b containing the -NH(CH2)2NH- and the -NH(CH2)4NH- linkers between two G3 dendrons, respectively, do not show any LC phases on thermal treatment. Computational investigations on molecular conformations reveal that N-methylation of the dendritic central linker leads dendrimers to possess more isomeric conformations and thus successfully converts non-LC dendrimers (1a and 1b) into LC dendrimers (2a and 2b).

Abstract
Recognition and binding of anions in water is difficult due to the ability of water molecules to form strong hydrogen bonds and to solvate the anions. The complexation of two different carboxylates with 1-(4-carbomethoxypyrrolidone)-terminated PAMAM dendrimers was studied in aqueous solution using NMR and ITC binding models. Sodium 2-naphthoate and sodium 3-hydroxy-2-naphthoate were chosen as carboxylate model compounds, since they carry structural similarities to many non-steroidal anti-inflammatory drugs and they possess only a limited number of functional groups, making them ideal to study the carboxylate-dendrimer interaction selectively. The binding stoichiometry for 3-hydroxy-2-naphthoate was found to be two strongly bound guest molecules per dendrimer and an additional 40 molecules with weak binding affinity. The NOESY NMR showed a clear binding correlation of sodium 3-hydroxy-2-naphthoate with the lyophilic dendrimer core, possibly with the two high affinity guest molecules. In comparison, sodium 2-naphthoate showed a weaker binding strength and had a stoichiometry of two guests per dendrimer with no additional weakly bound guests. This stronger dendrimer interaction with sodium 3-hydroxy-2-naphthoate is possibly a result of the additional interactions of the dendrimer with the extra hydroxyl group and an internal stabilization of the negative charge due to the hydroxyl group. These findings illustrate the potential of the G4 1-(4-carbomethoxy) pyrrolidone dendrimer to complex carboxylate guests in water and act as a possible carrier of such molecules.
