A photoluminescence (PL)-based oxygen and glucose sensor utilizing inorganic or organic light emitting diode as the light source, and polythiophene: fullerene type bulk-heterojunction devices as photodetectors, for both intensity and decay-time based monitoring of the sensing element's PL. The sensing element is based on the oxygen-sensitive dye Pt-octaethylporphyrin embedded in a polystyrene m...

A novel polythiophene derivative, poly[3-(5-octyl-thienylene-vinyl)-thiophene] (POTVT) with conjugated thienylene vinyl side-chain, was synthesized, and the POTVT film shows a very broad absorption band-width covering from 300 nm to 700 nm after thermal annealing at 130 degrees C for 10 min.

The synthesis of nanocrystal-polymer nanocomposites is reported, in which 2-(2-ethoxyethoxy)ethoxy modified polythiophene serves as the protecting group for dispersion and homogeneous size distribution of the nanoparticles, showing potential of this polymer-based material in optoelectronics and microelectronics.

We describe the capsulation of colloidally templated polythiophene (P3-TAA) arrays with multi-walled carbon nanotubes (MWNTs) after colloidal template electropolymerization. The dissolution of the polystyrene (PS) particle templates, which were assembled via the Langmuir-Blodgett (LB)-like technique, allowed the formation of hollow-shell Janus type arrays.

Interring twisting (change in the dihedral angle between conjugated rings) of polythiophene was studied theoretically using periodic boundary conditions (PBC) at the B3LYP/6-31G(d) level. We find that the band gap of polymers is strongly dependent on the interring twist angle; yet twisting requires very little energy. A twist of 30 degrees increases the band gap by 0.75 eV in polythiophene, whi...

We have fabricated inverted heterojunction solar cell devices incorporating [6,6]-phenyl-C(61)-butyric acid methyl ester/poly(3-hexylthiophene) core/shell nanorod arrays by using an anodic alumina oxide template. The internal quantum efficiencies and external quantum efficiencies of these core/shell nanorod inverted solar cells were higher than those of the corresponding conventional inverted b...

An amphiphilic polythiophene-based chemosensor shows optical changes accompanied by the formation of random coils (i.e., fireworks) from backbone-planarized structures upon addition target oxyanions such as pyrophosphate and citrate. The difference in responses to enables pattern recognition-based discrimination a mixture. More information can be found Research Article Tsuyoshi Minami et al.
