TECHNOLOGY FOCUS - ELECTRONICS - Preferred Components: The active layer of photovoltaic device further comprises electron donor polymers, optionally polythiophenes.    TECHNOLOGY FOCUS - POLYMERS - Preparation (Disclosed): Preparation of copolymeric materials comprises employing condensation reaction between alpha -reactive modified poly(quinoline)s and omega -end hydroxy regioregular poly(3-alkyl thiophene)s or terthiophenes. Preferred Components: The copolymeric materials are with the architecture of the random copolymers of formula (I) or the rod-coil block copolymers of formula (IIa), the coil-coil block copolymers of formula (IIb), or the brush type rod-coil copolymers of formula (IIc). The hybrid materials (h1) comprise hybrid electron acceptors of formula (III). The hybrid materials (h2) comprise hybrid donor-acceptor copolymers of formula (IVa), (IVb), (IVc) and (IVd).R2 = H;R3 = H or CnH2n+1;R1, R11 = fluoro or perfluoro substituted phenyls, pyridinyl, CN or nitro substituted phenyls;n = not defined;x = 1-50%;y = 50-99%;m = 3-150 repeating units;A1 = O;B1 = -COR;R = aryl or alkyl;R12 = H;R13 = CnH2n+1;k = 3-150 repeating units;l = 5-100 repeating units;p = 1-25 repeating units;q = 5-100 repeating units;A2 = -OC(=O)R-;B2 = none;r = 20-150 repeating units;s = 1-20 repeating units;t = 5-50%;u = 95-50%;R4 = H or F;v = 10-100%;w = 90-0%;e = 3-20 repeating units;f = 0-30 repeating units; andR5 = -aryl-NH-, -aryl-O-CO-CH(CH3)- or 2,3,5,6-tetrafluorophenyl-1-azabicyclo. EXAMPLE - 135.18 mg 6-(4-Vinylphenyl)-2-perfluorophenyl-4-phenyl quinoline, 50 mg 2-(5-(thiophene-2-yl)thiophen-2-yl)-5-(4-vinylphenyl) thiophene, 4.69 mg azoisobutyronitrile and 5 ml distilled tetrahydrofuran were added to a degassed flask equipped with condenser. The reaction mixture was degassed, filled with argon and then refluxed for 48 hours. After cooling to room temperature the viscous mixture was precipitated in methanol and the solid was filtered and washed with methanol. The final polymer was dried at 60 degrees C under high vacuum for 24 hours to obtain the random copolymers of formula (VI) (where x is 33.3 and y is 66.7).
