The Correlation of Electrochromic Color Shifts with the Stoichiometric Parameters of Selected Copolymers and Polymer Blends

Abstract

Three copolymers of N-vinylcarbazole and N-phenyl-2-(5' -vinyl-2'-thienyl)-5-(2"-thienyl)-pyrrole were synthesized using different feed stock ratios identical to the mass blends and characterized. Blends of poly(N-vinylcarbazole) (PVK) and poly(N-phenyl-2-(2'-thienyl)-5-(5"-vinyl-2"-thienyl)pyrrole) (PSNPhS) with similar compositions were prepared. Solid state devices were fabricated, and the electrochromic properties of both systems were studied. In-situ spectroelectrochemistry and spectrocolorimeter measurements reveal that the electrochromic properties of these devices can be correlated with the ratio of the comonomers present. The observed color changes in the doped state of the devices were also correlated to the reflectance spectra.
