Structural studies of copper(II)-amine terminated dendrimer complexes by EXAFAS
Article Abstract:
The interaction of amine-terminated polyamido(amine), PAMAM, dendrimer with copper(II) ions determined by extended X-ray absorption fine structure (EXAFS) is reported. The results suggest that the model consisting of the copper(II) ion forming five- and six- membered rings by chelating with the primary amine, amide, and tertiary amine nitrogen doors of the PAMAM dendrimer could describe the experimental EXAFS data well.

Electrochemical actuation of growing copper dendrimers in water
Article Abstract:
The observation of electrochemical actuation in growing dendritic fibers made of self-assembled copper nanostructures, on the metallic cathode of an ordinary aqueous electrochemical cell is reported. The extent of actuation is found to be dependent on the applied voltage, the concentration of [Cu.sup.2+] ions in the solution, and also on ions such as [Na.sup.+], which did not get deposited at the cathode.

Light-harvesting in carbonyl-terminated phenylacetylene dendrimers: The role of delocalized excited states and the scaling of light-harvesting efficiency with dendrimer size
Article Abstract:
Steady-state and time-resolved optical spectroscopy was employed to study the photophysics of a family of conjugated phenylacetylene (PA) light-harvesting dendrimers. It was found that this class of molecules has several unique photophysical properties that affect their utility as light-harvesting compound.
