Photoresponse of a single poly(p-phenylene vinylene)-CdSe bulk-heterojunction submicron fiber

Bulk-heterojunction PPV (poly(p-phenylene vinylene))-CdSe submicron fibers have been prepared by introducing electrostatic interaction between thioglycolic acid capped CdSe nanocrystals and PPV precursor, subsequently with electrospinning and thermal conv

Detection of TNT based on conjugated polymer encapsulated in mesoporous silica nanoparticles through FRET

Amine-functionalized mesoporous silica nanoparticles containing poly(p-phenylenevinylene) provide a facile strategy to detect TNT through fluorescence resonance energy transfer (FRET). The observed linear fluorescence intensity change allows the quantitat

Aqueous-solution-processed PPV-CdxHg1-xTe hybrid solar cells with a significant near-infrared contribution

Aqueous poly(p-phenylene-vinylene) (PPV):CdxHg1-xTe nanocrystal (NC) hybrid solar cells are prepared with heat-introduced aggregation and growth of the NCs. The morphology of the active layer is easily controlled by tuning the compos

Discovery of an anionic polymerization mechanism for high molecular weight PPV derivatives via the sulfinyl precursor route

The polymerization of PPV via the sulfinyl precursor route has been investigated with respect to its mechanism. When polymerized in sec-butanol, a purely radical polymerization mechanism is observed as in most precursor polymerization routes. Accordingly,

IR and Submillimetre-wave Spectra of Doped Poly(p-phenylene vinylene)

Poly(p-phenylene vinylene) (PPV) films of varying thickness have been prepared using standard precursor routes.A new oxidative doping technique, using degassed concentrated H2SO4 under low pressure, was used.Precise levels of doping were achieved, these l

Macro-counterions in a precursor to poly(phenylene vinylene): Toward defect-free luminescent films

Thermal elimination of a water soluble poly(xylylidene) precursor to poly(phenylene vinylene) (PPV) was accomplished in air at 80 °C using the macro-counterion poly(ethylene glycol)-4-nonylphenyl-3-sulfopropyl ether (PEGNOPS). The high relative photolumin

SWITCHABLE ANTIFOULING COATINGS AND USES THEREOF

The present invention relates to antifouling coatings capable of being switched by using heat or ultraviolet light. Prior to switching, the coating includes an onium cation component having antimicrobial and antibacterial properties. Upon switching, the c

Synthesis and dry-spinning fibers of sulfinyl-based poly(p-phenylene vinylene) (ppv) for semi-conductive textile applications

Soluble, processable sulfinyl-based poly(p-phenylene vinylene) (PPV) precursors were synthesized, and the first sulfinyl-based PPV fibers were subsequently spun on a dry-spinning apparatus. 1-(Chloromethyl)-4-[(n- octylsulfinyl)methyl]benzene was synthesi

Highly Selective Route for Producing Unsymmetrically Substituted Monomers toward Synthesis of Conjugated Polymers Derived from Poly(p-phenylene vinylene)

A new convenient route for producing unsymmetrically substituted sulfinyl monomers of precursor polymers toward poly(p-phenylene vinylene) is described. Upon treating a symmetrical bissulfonium salt with a thiolate anion, an unexpected high selectivity for the monosubstituted thioethers (90%) is obtained. Optimization of the reaction conditions showed that the stoichiometry of the reactants in this reaction is important to ensure the high selectivity and to prevent unwanted side reactions. Reaction of equimolar amounts of reagents at ambient temperature gave the best results. A mechanism consistent with these results, supported by UV-vis experiments, is presented. Selective oxidation of the thioethers yielded the sulfinyl monomers. By using this new route, it was possible to increase the overall yield by a factor of 2, as compared to the route previously used to obtain these compounds.
