<P>Two novel alternating π-conjugated copolymers, poly[2,8-(6,6′,12,12′-tetraoctyl-6,12-dihydroindeno-[1,2b]fluorene- alt-5(1-(2,6-diisopropylphenyl)-2,5-di(2-thienyl)pyrrole) (P1) and poly[2,8-(6,6′,12,12′-tetraoctyl-6,12-dihydroindeno-[1,2b]fluorene- alt-5(1-(p-octylphenyl)-2,5-di(2-thienyl)pyrrole) (P2), were synthesized via the Suzuki coupling method and their optoelectronic properties were investigated. The resulting polymers P1 and P2 were completely soluble in various common organic solvents and their weight-average molecular weights (M<SUB>w</SUB>) were 5.66 × 10<SUP>4</SUP> (polydispersity: 1.97) and 2.13× 10<SUP>4</SUP> (polydispersity: 1.54), respectively. Bulk heterojunction (BHJ) solar cells were fabricated in ITO/PEDOT:PSS/polymer:PC<SUB>70</SUB>BM(1:5)/TiO<SUB>x</SUB>/Al configurations. The BHJ solar cell with P1:PC<SUB>70</SUB>BM (1:5) has a power conversion efficiency (PCE) of 1.12% (J<SUB>sc</SUB>= 3.39 mA/cm<SUP>2</SUP>, V<SUB>oc</SUB>= 0.67 V, FF = 49.31%), measured using AM 1.5 G solar simulator at 100 mW/cm<SUP>2</SUP> light illumination. We fabricated polymer light-emitting diodes (PLEDs) in ITO/PEDOT:PSS/emitting polymer:polyethylene glycol (PEG)/Ba/Al configurations. The electroluminescence (EL) maxima of the fabricated PLEDs varied from 526 nm to 556 nm depending on the ratio of the polymer to PEG. The turn-on voltages of the PLEDs were in the range of 3–8 V depending on the ratio of the polymer to PEG, and the maximum brightness and luminance efficiency were 2103 cd/m<SUP>2</SUP> and 0.37 cd/A at 12 V, respectively. © 2010 Wiley Periodicals, Inc.

A new crosslinkable polythiophene derivative, poly(hexynyl2-PDOT-co-heptyl2-PDOT), with propylenedioxythiophene moiety containing solubilizing and crosslinkable substitutents as a pendant group were synthesized by oxidative polymerization using FeCl3. The resulting copolymer was soluble in organic solvents and spun cast onto the indium tin oxide-coated glass substrate to create a uniform thin film. After thermal crosslinking and rinsing of the crosslinked thin film using chloroform, the π-π transition peak and the absorption edge appeared at almost the same wavelength as that of the untreated copolymer. We fabricated organic light-emitting diodes (OLEDs) in ITO/buffer layer/poly[2-(2'-ethylhexyloxy)-5-methoxy-1,4-phenylenevinylene] (MEH-PPV)/LiF/Ca/Al configuration using either poly(3,4-ethylenedioxythiophene) doped with poly(styrenesulfonate) (PEDOT:PSS) or poly(hexynyl2-PDOT-co-heptyl2-PDOT) as buffer layers. Due to the intrinsic conductivity of poly(hexynyl2-PDOT-co-heptyl2-PDOT) vs. that of PEDOT:PSS caused decreased OLED performance. The turn-on voltage of the OLED using poly(hexynyl2-PDOT-co-heptyl2-PDOT) buffer layer was observed at 5 V. The maximum brightness and luminance efficiencies were 2,597 cd/m2 at 12 V and 0.3 cd/A, respectively.
