We use a high harmonic generated supercontinuum in the soft X-ray region to measure X-ray absorption near edge structure (XANES) spectra in polythiophene (poly(3-hexylthiophene)) films at multiple absorption edges. A few-cycle carrier-envelope phase-stable laser pulse centered at 1800 nm was used to generate a stable soft X-ray supercontinuum, with amplitude gating limiting the generated pulse ...

Gold nanoparticles have attracted intense interest in materials and physical chemistry since the development of simple solution-phase methods for their synthesis and stabilization. The unique physical properties of gold nanoparticles have created a wide variety of potential applications including biological markers, DNA sensors, molecular recognition systems and nanoscale electronics. Encapsula...

A convenient method of introducing pentafluorobenzene (PFB) as a single end-group in polythiophene derivatives is reported via in situ quenching of the polymerization. We demonstrate that the PFB-group is a particularly useful end-group due to its ability to undergo fast nucleophilic aromatic substitutions. Using this molecular handle, we are able to quantitatively tether a variety of common nu...

The intermediate neglect of differential overlap (INDO) band structures of polythiophene, polyfuran, and polypyrrole are analyzed in terms of the band structure of polyacetylene. This is done by decoupling the INDO Fock operator to obtain the band structure of the carbon system and of the heteroatoms. For all three polymer systems, the highest valence band is essentially a pure carbon band, whe...

We report a chlorine-substituted polythiophene-based, dioxobenzodithiophene-containing conjugated polymer (P2T-Cl) as promising dopant-free hole transport material in lead halide perovskite solar cells.

The high demand for efficient energy devices leads to the rapid development of storage systems with excellent electrochemical properties, such as long life cycles, cycling stability, and power density. SC is postulated a potential candidate fulfill this demand. combination graphene polyaniline can create electrodes electrical conductivity, specific surface area, capacitance. graphene/polyanilin...

The reaction of 3-lithiothiophene with alkyl chloromethyl ether yielded 3-alkoxymethylthiophenes, which were electrochemically polymerized to give conducting polymer films. The conductivity of poly(3-ethoxymethylthiophene) was higher than that of poly(3methoxymethylthiophene), indicated that a longer side chain homologue exceptionally shows higher conductivity. keywords: Electrochemical polymer...

A colorimetric assay for convenient detection of miRNA and RNase H activity was established in a homogeneous and label-free manner based on conformational and colorimetric changes of a polythiophene derivative (PMNT) in the duplex of DNA/PMNT and triplex of DNA/miRNA/PMNT.

Although the charge separation (CS) and transport processes that compete with geminate and non-geminate recombination are commonly regarded as the governing factors of organic photovoltaic (OPV) efficiency, the details of the CS mechanism remain largely unexplored. Here we provide a systematic investigation on the role of local charge carrier mobility in bulk heterojunction films of ten differe...
