Electron n-doping of a highly electron-deficient chlorinated benzodifurandione-based oligophenylene vinylene polymer using benzyl viologen radical cations

Successful electron-doping of highly electron-deficient chlorinated benzodifurandione-based polyphenylene vinylene using viologen radical cation.

On-surface reductive coupling of aldehydes on Au(111)

A reductive process allows to covalently couple aldehydes on a Au(111) surface. While oxygen desorbs completely during the reaction, a strongly interlinked polyphenylene vinylene derivative is formed, remaining weakly adsorbed on the surface.

The role of structural fluctuations and environmental noise in the electron/hole separation kinetics at organic polymer bulk-heterojunction interfaces

We investigate the electronic dynamics of a model organic photovoltaic (OPV) system consisting of polyphenylene vinylene (PPV) oligomers and a [6,6]-phenyl C61-butyric acid methylester (PCBM) blend using a mixed molecular mechanics/quantum mechanics (MM/QM) approach.

The Synthesis and Characterization of Polyphenylene Vinylene (PPV) Derivatives with Alkoxy Branched Chains

Polyphenylene vinylene derivatives with various alkoxy branched chains, including PMOBOPV,PMOCOPV,iso-PMOCOPV and PMODOPV,were synthesized via a dehydrochlorination route,and characterized by FTIR,HNMR,DSC,TGA,UV-Visible and fluorescence spectroscopy. The result indicated that as-prepared polymers were of remarkable thermal stability and solubility in common solvent with the maximum UV absorption peak at ~492nm and light emission at ~555 nm.
