Thermodynamic study of ion-pairing effects between reduced double-decker lutetium(III) phthalocyanines and a cationic matrix

Article Abstract:

Studies done on the thermodynamics of ion paring between electrochemically reduced [(C6H13S)8Pc]2Lu or [(C12H25S)4Pc]2 Lu and a cationic tetra-n-octylphosphonium bromide (4C8P+Br-) matrix is reported. Findings reveal that the thermodynamic treatment is applicable not only to reduced double-decker lutetium(III) phthalocyanines but also to other highly reduced compounds such as porphyrins and fullerenes.

Characterization of photoelectrocatalytic processes at nanoporous TiO2 film electrodes: photocatalytic oxidation of glucose

Article Abstract:

The effect of potential bias, light intensity, and the concentration of the photohole scavenger (glucose) on the photocurrent responses of the nanoporous TiO2 film electrodes is studied focusing on the overall photoelectrocatalytic oxidation process. It was observed that at high glucose concentrations the photocurrent increases linearly with potential positive of the zero current potential.

Coverage dependent evolution of two-dimensional dendrimer/mica domain patterns

Article Abstract:

Study of the domain pattern evolution for the case of dendrimer molecules on mica, a materials system amenable to control of the competing interactions is reported. The domain patterns were fabricated by simple aerosol deposition of dilute solutions of dendrimer molecules in pentanol under ambient conditions followed by slow evaporation.
