Segmented block copolymers (BCPs) of conjugated distyrylbenzene conjugated units linked by variable flexible nonconjugated units were p-doped, and their electrical conduction and Seebeck thermoelectric (TE) behaviors evaluated. The doped BCP Seebeck coefficients ranged up about 2600μVK −1 , but with low conductivities giving low TE power factors. BCP blends with MEH-PPV gave much improved...
Poly(para-phenylenevinylene-alt-3-tert-butyl-meta-phenylenevinylene) was synthesized by Wittig condensation with varying ratio of cis and trans olefin bonds. The luminescent properties of the unisomerized and trans-isomerized polymers (1 and 2, respectively) were compared. Nearly identical emission spectra were observed for both polymers in dilute solutions, but the emission intensity of 1 is lower...
