Abstract
Sensitization and binding of a large footprint pyrene chromophore to planar (sapphire) and colloidal metal oxide films (TiO2 and ZrO2) is investigated. The model compound combines a 1-pyrenyl-ethynylenephenylene unit with a new adamantane-tripodal linker that binds to the surface. The linker design, combining a large footprint (approximately 2 nm2) of the tripodal linker with the meta position of the COOH anchoring groups, was suggested from atomistic models, and it aims to provide improved spacing control. The pyrene chromophore unit provides a probe of sensitizer-sensitizer interactions through its propensity to form excimers, unless neighboring pyrene units are sufficiently spaced (>or=3.5 A). Absorption and fluorescence studies, and a comparison with a pyrene-rigid rod model compound, suggest that the new tripodal anchor group allows spacing control on planar surfaces. On colloidal films, the linker provides spacing control at low surface coverage but sensitizer-sensitizer interactions are still observed on colloidal films at high surface coverage. Implications for the functionalization of metal oxide films in hybrid molecule-metal oxide semiconductor material systems are discussed.

Abstract
We report on the application of a poly(methyl acrylate)/poly(ethylene glycol)-based polymer gel electrolyte and triphenylamine-based metal-free organic dyes in quasi-solid-state dye-sensitized solar cells. The poly(methyl acrylate)/poly(ethylene glycol) hybrid is beneficial to the entrapment of a large volume of liquid electrolyte. At 25 degrees C, the ionic conductivity and the triiodide ionic diffusion constant of the as-prepared polymer gel electrolyte are 2.1 mS cm(-1) and 2.3 x 10(-6) cm(2) s(-1), respectively. The quasi-solid-state solar cell sensitized by triphenylamine-based dyes attains an overall energy conversion efficiency of 5.76% at a light intensity of 30 mW cm(-2). The presence of poly(ethylene glycol) in the electrolyte obviously increases the conductivity and energy conversion efficiency compared to that without poly(ethylene glycol).
