dc.description.abstract2-Dodecyl benzotriazole and 9,9-dioctylfluorene containing alternating copolymers poly((9,9-dioctylfluorene)-2,7-diyl-(2-dodecyl-benzo[1,2,3]triazole)) (P1), poly((9,9-dioctylfluorene)-2,7-diyl-(4,7-bis(thien-2-yl) 2-dodecyl-benzo[1,2,3]triazole)) (P2), poly((9,9-dioctylfluorene)-2,7-diyl-(4,7- bis(3-hexylthien-5-yl) 2-dodecyl benzo[1,2,3]triazole)) (P3) were synthesized via a typical Suzuki coupling polymerization. UVvis and electrochemical studies indicated that polymers have desirable HOMOLUMO and band gap energy levels, enabling efficient electron transfer when blending them with fullerene derivatives. Photovoltaic properties of the copolymers mixed with [6,6] phenyl-C61-butyric acid methyl ester (PCBM), were investigated. P2 exhibited the best device performance with an open circuit voltage of 0.6 V, short circuit current of 3.4 mA/cm 2 and power conversion efficiency of 0.56% under Air mass 1.5 Global (AM 1.5G, 100 mW/cm 2) illumination. Hole mobilities of the polymers were calculated using space charge limited current (SCLC) method and found to be in the order of 10 -5 for P1 and P2 and 10 -4 for P3. © 2011 Elsevier B.V.
