Preparation, Optical Properties and Yellow Electroluminescence of Water-Soluble Poly(p-phenylene vinylene)

Abstract

Novel carboxy-substituted poly( p -phenylene vinylene), poly(1,4-(2-(5-carboxypentyloxy)-5-methoxyphenylene)vinylene) (CPMOPPV) has been synthesized. The obtained polymer is soluble in organic solvents, such as acetone and ethanol, and the sodium salt of CPMOPPV is soluble even in water. The optical properties of CPMOPPV, such as optical absorption and photoluminescence have been studied, and yellow-electroluminescence devices have been fabricated. The electronic energy structure of CPMOPPV has been determined by optical and electrochemical measurements. CPMOPPV has been demonstrated to be one of the candidate polyanions for fabrication of the organic multilayer structure by the self-assembly technique.
