Electro Optical Properties of Copolymer Blends
Abstract
A number of investigations concerning the synthesis, characterization and properties of electro-optical macromolecules has been completed. A wide range of structures mostly based on a conjugated main chain and focused on providing high photo-luminescent and electroluminescent quantum yields, were produced and fabricated into opto-electronic devices. Parallel investigations have continued the long established study of polymer blends by various physical means. Amongst others, a dielectric relaxation study has compared the properties of a prototypical blend with that of a statistical copolymer of equal overall composition to probe the dimensions of micro-heterogeneity in such systems. Further studies of the below-(-) temperature collapse (coil-globule) transition in solvated polymer chains has included polyelectrolyte systems. Some 46 papers were published or were in press during the grant period.
