Structure and excitation relaxation dynamics of dimethylanthracene dimer in a gamma-cyclodextrin nanocavity in aqueous solution
Article Abstract:
The excitation relaxation dynamics of dimethylanthracene (DMA) in aqueous solutions in the presence of [alpha]-, [beta]-, and [gamma]-CDs was studied and it was found that there are both hydrated and anhydrated species of DMA in the [alpha]- and [gamma]-CD nanocavities. The structure of anhydrated (DMA)2-([gamma]-CD)2 is configured from the [(sup.1).B.sub.b] exciton splitting observed in the fluorescence excitation spectrum with the help of LJ + Coulombic potential calculations.

Altering associations in aqueous solutions of a hydrophobically modified alginate in the presence of beta-cyclodextrin monomers
Article Abstract:
The effect of beta-cyclodextrin (beta-CD) in addition to the hydrophobically modified alginate (HM-alginate) solutions is presented by evaluating the reversibility of the hydrophobic polymer interactions and the change in the polymer conformation. The inclusion inside the beta-CD cavities of the normally associating polymer side groups reduces the steady sheer viscosity and the dynamic moduli of the HM-alginate solutions.

Electrodeposition of poly(N-vinylcarbazole) at the three-phase junction: Formation of very different polymer structures
Article Abstract:
The three-phase electrooxidation of the N-vinylcarbazole monomer that is present only in the supporting electrolyte free-organic phase is described. The method allows the determination of the depth of penetration of anions from the aqueous phase into the organic phase and also allows the deposition of polymers of different forms such as collars, cylinders, and semicrystals.
