Abstract
Hybrid materials take advantage of the unique properties of two single-phase materials (e.g., organic and inorganic) by bonding these materials together, producing a two-phase material with properties that cannot be achieved by a single-phase material. In this study, a set of hybrid materials were synthesized for deposition via Functionalized Carboxylate Deposition (FCD), a novel gas-phase deposition technique developed in our laboratory, for use in dye sensitized solar cell (DSSC) and chromatography applications. FCD-compatible ruthenium dye complexes were synthesized based on conventional DSSC dyes (N3 and N719). These dyes were modified with cyano-acrylic groups (CAA) to form N3-CAA and N719-CAA dyes. Synthesis was accomplished by initially oxidizing a bipyridine dimethanol ligand and using Knoevenagel condensation to introduce CAA functionality. These dyes produced efficiencies of 1.4-1.5%. Organic bonded phases were similarly synthesized for application as chromatographic stationary phases. 2-cyano 3-phenyl acrylic acid (CPA), 2-cyano 3-pentaflorophynyl acrylic acids (CFA), 2-cyano hexenic acid (2-CHeA), 2-cyano hexanoic acid (2-CHaA) hybrid molecules were synthesized via Knoevenagel condensation of their corresponding aldehyde precursors. The resulting compounds were deposited on silica solid support materials and the chromatographic behavior of methyl violet using the novel stationary phases was evaluated.
