    • Novel soluble, fast doping and de-doping, conductive, electroluminescent π-conjugated homo- and co-polymers comprise poly(phenylene vinylene) polymers of chemical formula (I), wherein R' is the same of 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 is described by exposing an amount of a dopant to at least one poly(phenylene vinylene) polymer. An improved method of transducing electric energy into visible light by means of a light-emitting diode (LED) is described.
