“…The resulting regiosymmetric polymer, poly(PDOT), had high solubility in common organic solvents and fairly good conductivity with low optical absorption in the visible region . More recently, we reported the synthesis of a new series of statistical copolymers with poly(9,9-dialkylfluorenyl-2,7-vinylene), poly(FV), and highly luminescent poly[2-(3-dimethyldodecylsilylphenyl)-1,4-phenylenevinylene], poly( m- SiPhPV), using the Gilch polymerization method. − The introduction of the bulky dimethyldodecylsilylphenyl substitutents on the phenyl side group in the PPV backbone reduces the intermolecular interactions between the resulting polymer chains, which improves device performance. − In the present study, we used Gilch polymerization to generate a novel PPV-based homopolymer with a PDOT moiety as a side chain, poly[1,4-{2-(3‘,3‘-diheptyl-3,4-propylenedioxythiophen-2-yl)}phenylenevinylene], poly(PDOT−PV), and statistical copolymers, poly(PDOT−PV- co - m -SiPhPV), with poly( m- SiPhPV) segments. These new polymers have good solubility and high molecular weights.…”

Using the Gilch polymerization method, we synthesized a new series of green electroluminescent polymer, poly[1,4-{2-(3,3‘-diheptyl-3,4-propylenedioxythiophen-2-yl)}phenylenevinylene], poly(PDOT−PV), which is a series of fully conjugated poly(p-phenylenevinylene) derivatives with a propylenedioxythiophene (PDOT) moiety as a side-chain. We also synthesized copolymers, poly(PDOT−PV-co-m-SiPhPV), of poly(PDOT−PV) with poly[2-(3-dimethyldodecylsilyphenyl)-1,4-phenylenevinylene], poly(m-SiPhPV), segments. The resulting polymers were highly soluble in common organic solvents and could be easily spin-coated onto an indium−tin oxide coated glass substrate to obtain high quality optical thin films. The weight-average molecular weight (M w) and polydispersity of poly(PDOT−PV) were 22.0 × 104 and 5.3, respectively, and those of poly(PDOT−PV-co-m-SiPhPV) were in the ranges (23.2−36.7) × 104 and 5.0−5.8, respectively. The stability of the resulting polymers is adequate for the fabrication of devices, and they provide longevity to devices because they have high glass transition temperatures (T g). We fabricated polymer light-emitting diodes (PLEDs) in ITO/PEDOT/light-emitting polymer/cathode configurations using either double-layer LiF/Al or triple-layer Alq3/LiF/Al cathode structures. For PLEDs containing poly(PDOT−PV) and poly(PDOT−PV-co-m-SiPhPV), the performance was highest using triple-layer cathodes. The turn-on voltages of PDOT-based light-emitting polymers were in the range of 6.0−9.0 V, and the maximum brightness and luminance efficiency were 5127 cd/m2 at 18 V and 3.75 cd/A at 9 V.

Four new fluorescent conjugated vinylene‐copolymers incorporating quinoline or bisquinoline segments along the backbone were synthesized by Heck coupling. Three of them were fluorenevinylene‐copolymers and contained quinoline (PQFV, PQFVT) or bisquinoline segments (PBQFV). One of them (PBQPV) was phenylenevinylene‐copolymer and contained bisquinoline segments. All the copolymers were soluble in common organic solvents and had relatively low glass transition temperature (Tg = 50–56 °C for fluorenevinylenes and Tg < 25 °C for phenylenevinylene). In THF solutions, the quinoline‐containing copolymers showed absorption maxima at 411–420 nm while the bisquinoline‐containing ones exhibited maxima at 357–361 nm. The emission maxima of solutions were 465–490 nm. The copolymers showed high quantum yields up to 64%. The films exhibited absorption and emission maxima in the range of 371–437 nm and 480–521 nm, respectively. All copolymers revealed reversible reduction with electron affinity of 2.66–3.53 eV and irreversible oxidation scans with ionization potential of 5.39–5.53 eV. © 2009 Wiley Periodicals, Inc.
