The Stability of Cyclodextrin Complexes in Solution.

This Account reports the synthesis and characterization of dendrimer-encapsulated metal nanoparticles and their applications to catalysis. These materials are prepared by sequestering metal ions within dendrimers followed by chemical reduction to yield the corresponding zerovalent metal nanoparticle. The size of such particles depends on the number of metal ions initially loaded into the dendrimer. Intradendrimer hydrogenation and carbon−carbon coupling reactions in water, organic solvents, biphasic fluorous/organic solvents, and supercritical CO2 are also described.

Dendrimer-Encapsulated Metal Nanoparticles: Synthesis, Characterization, and Applications to Catalysis

Methods for Selective Modifications of Cyclodextrins.

Cyclodextrin-based polymeric materials: synthesis, properties, and pharmaceutical/biomedical applications.

The interaction of copper(II/I) complexes of a few 2,9-dimethyl-1,10-phenanthrolines with calf thymus DNA has been investigated using absorption and circular dichroic spectral and electrochemical techniques and viscometry. The observation of the usual hypochromism and the novel hyperchromism in the absorption spectra of [CuI(bcp)2]+ [bcp = 2,9-dimethyl-4,7-diphenyl-1,10- phenanthroline] and [CuI(dpsmp)2]3- [dpsmp2- = 2,9-dimethyl-4,7-bis(sulfonatophenyl)-1,10-phenanthroline] respectively in the presence of DNA and the increase in viscosity of DNA at low loadings of both these complexes have been interpreted in terms of bridging of a pair of DNA duplexes by the complex species. These tetrahedral copper(I) complexes, which lack minor groove binding because of substituents at the 4- and 7-positions of phen ring, are efficient in bridging the duplexes. The electrochemical behaviors of [CuI(dmp)2]+ [dmp = 2,9-dimethyl-1,10-phenanthroline] and [CuI(bcp)2]+ bound to DNA have been compared with that of the analog...
