摘要

Novel soluble, fast doping and de-doping, conductive, electroluminescent pi -conjugated homo- and co-polymers comprise poly(phenylene vinylene) polymers of the chemical formula (I) wherein R' is the same or different and is selected from the group consisting of hydrogen, (C1-C10)alkyl, alkenyl, and alkynyl, (C6-C30)aryl, cycloalkyl, cycloalkenyl and cycloalkynyl, (C7-C40)arylalkyl, arylalkenyl, arylalkynyl, alkyl, alkenyl and alkynyl cycloalkyl, alkyl, alkenyl, and alkynyl cycloalkenyl, and alkyl, alkenyl and alkynyl cycloalkynyl, -OR''' and combinations thereof, wherein R''' is selected from the group consisting of (C6-C30)hydrocarbons comprising branched alkyl, alkenyl, alkynyl, cycloalkyl, cycloalkenyl and cycloalkynyl, mono- and poly-hydroxylated derivatives thereof, (C1-C10)esters and ethers thereof, and (C5-C30)carbohydrates comprising furanosyl, pyranosyl, and oligomers thereof, (C1-C10)ethers and esters thereof, and combinations thereof, R'' is hydrogen or methyl, A is O,C,S, N or a single bond, n is 1 to 4, m is 1 to 4, o is 1 to 2, x>1, y>0, and x+y>20. These polymers are useful in the manufacture of electrostatic and electromagnetic interference shields, molded articles, and especially in electroluminescent layers, films and fibers for use in light-emitting diodes (LEDs) for technical devices. A method for sensing a dopant within a designated area comprises exposing an amount of a dopant present within a designated area to at least one poly(phenylene vinylene) polymer of this invention for a period of time effective to allow the uptake of the dopant to be sensed by the polymer; and measuring the conductivity of the polymer and correlating the conductivity to the amount of dopant present within the designated area. An improved method of transducing electric energy into visible light by means of a light-emitting diode (LED) comprising a metallic contact, an electron transport layer and a semiconductive layer, the improvement wherein the semiconductive layer is formed from the polymer of the invention.
