Hydrogen evolution at conjugated polymer nanoparticle electrodes

Fortin, Patrick; Rajasekar, Subash; Chowdhury, Pankaj; Holdcroft, Steven

Organic polymer nanoparticles have been gaining attention in photovoltaics as a means to control the morphology of polymer composite films for the purpose of studying bulk heterojunction, photoactive layers. This work investigates the preparation of nanostructured organic thin films from P3HT:PC61BM nanoparticles and their characterization as photoelectrodes for the photoelectrochemical…

Switchable Charge Injection Barrier in an Organic Supramolecular Semiconductor

We disclose a supramolecular material that combines semiconducting and dipolar functionalities. The material consists of a discotic semiconducting carbonyl-bridged triarylamine core, which is surrounded by three dipolar amide groups. In thin films, the material self-organizes in a hexagonal columnar fashion through π-stacking of the molecular core and hydrogen bonding between…

On cellulose dissolution and aggregation in aqueous tetrabutylammonium hydroxide

Gubitosi, Marta; Duarte, Hugo; Gentile, Luigi; Olsson, Ulf; Medronho, Bruno

Aqueous tetrabutylammonium hydroxide, TBAH(aq), has been found to dissolve cellulose and to be a potential solvent for chemical processing or fiber spinning. In this paper, we have investigated the dissolution state of cellulose in 40 wt % TBAH(aq) solvent, and present an extensive study of rheology, combined with static light…

Smectic liquid crystal Schlieren texture in rapidly cooled poly(butylene naphthalate)

Ding, Qian; Jehnichen, Dieter; Göbel, Michael; Soccio, Michelina; Lotti, Nadia; Cavallo, Dario; Androsch, René

The morphology of partially crystalline/ordered poly(butylene naphthalate) (PBN) forming on cooling the melt has been analyzed by polarized-light optical microscopy (POM) and microfocus-beam X-ray diffraction (XRD). Crystallization at rather low supercooling of the melt, at temperatures higher than about 200 °C, leads to slow and irregular spherulitic growth of β′-crystals, with…

Extensional Strain Hardening Induced by $ensuremath{pi}text{ensuremath{-}}ensuremath{pi}$ Interactions in Barely Entangled Polymer Chains: The Curious Case of Poly(4-vinylbiphenyl)

López-Barrón, Carlos R.; Zhou, Huaxing

Aromatic π−π interactions between phenyl groups of adjacent chains in poly(4-vinylbiphenyl) (PVBP) have profound effects on the dynamics of this polymer. We report two unexpected nonlinear viscoelastic responses of PVBP when subjected to uniaxial flow. One is the unprecedented observation of extensional strain hardening (SH) in a barely entangled polymer…
