TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Components: The first functionality at the second and fifth positions is same or different and is not halogen (preferably bromine). The first functionality is (a1), (b1), (c1), (d1), (e1), (f1) or (g1). The first functionality for the first thiophene monomer is prepared by metalation and/or transmetalation of hydrogen at the second and fifth positions. The transition metal is palladium or nickel.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Components: Each substituents of the first thiophene monomer comprises a chain of at least five carbons or heteroatoms, and each substituents of the second thiophene monomer comprises a chain of fewer than five carbons or heteroatoms. The first thiophene monomer is 3,4-dialkoxythiophene or dialkylenoxythiophene having functionalities at the second and fifth positions, where the functionalities include (a1), (b1), (c1), (d1), (e1), (f1) or (g1). The second thiophene monomer is 2,5-dialkoxythiophene having functionalities (which includes -X) at the second and fifth positions.    TECHNOLOGY FOCUS - POLYMERS - Preferred Process: The step (b) comprises Suzuki coupling, Negishi coupling, Kumada coupling, Stille coupling or Hiyama coupling. Preferred Components: The first thiophene monomer is of formula (I). The second thiophene monomer is of formula (II) or (III). The formed copolymer is an alternating copolymer of formula (IV) or (V) or a random copolymer of formula (VI) or (VII). The copolymer is soluble in non-aqueous organic solvents (including tetrahydrofuran, chloroform, alkylated benzene, halogenated benzene, N-methyl-pyrrolidone, dimethyl formamide, dimethylacetamide, dimethyl sulfoxide, methyl ethyl ketone, cyclohexanone, chloroform, dichloromethane, acetone, dioxane, ethyl acetate, ethyl benzoate, ethylene carbonate, propylene carbonate, 1,2-dimethoxy ethane, tetrahydropyran, anisole or fluorinated solvent). The copolymer is fluorinated. At least one substituent at the third or fourth position is a fluorinated substituent. The copolymer is intractable in toluene or xylene in its oxidized form. The copolymer is poly(3,4-bis(2-(2-butoxyethoxy)ethoxy)thiophene)-alt-3,4-ethylenedioxythiophene.M = (a1), (b1), (c1), (d1), (e1), (f1) or (g1);R1-R4 = alkyl, alkenyl, alkynyl or aryl (all optionally substituted), where in formula (II), R1 and R2 are alkylene group linking the 3- and 4-substituents; andn, m = not defined. EXAMPLE - A dry three-neck round bottom flask (25 ml) was flashed with nitrogen and charged with 3,4-bis(2-(2-butoxyethoxy)ethoxy)thiophene (1.07 g) and anhydrous tetrahydrofuran (THF, 15 ml. The reaction flask was chilled to -78 degrees C and tert.-butyl lithium (3.50 ml) was added dropwise. The reaction mixture was stirred for 1 hour at -78 degrees C and acetone dry ice bath was removed. After 15 minutes of stirring at 0 degrees C, the solution was chilled to -78 degrees C and stirring was continued for 5 minutes. Anhydrous zinc chloride (0.76 g) was added in one portion and completely dissolved after 30 minutes of stirring. The cooling bath was removed and the reaction mixture was allowed to warm to ambient temperature. 2,5-Dibromo-3,4-ethylenedioxythiophene (0.795 g) in THF (5 ml) was added to the reaction mixture, followed by the addition of 1,2-bis(diphenylphosphino)ethane (63.3 mg) and bis(1,5-cyclooctadiene)nickel(0) (18.2 mg). The reaction mixture was heated to 65 degrees C and stirred for 24 hours. The reaction mixture was precipitated into methanol to obtain poly(3,4-bis(2-(2-butoxyethoxy)ethoxy)thiophene)-alt-3,4-ethylenedioxythiophene.
