Organic photovoltaics incorporating fulleroisoquinolinones as n-type materials.

Fulleroisoquinolinones have been synthesized by palladium-catalyzed annulation of N-alkyl benzamides with C(60). A device incorporating fulleroisoquinolinones and the conjugated polymer P3HT exhibited power conversion efficiency up to 2.3% under AM 1.5G irradiation.

Flexible CMOS electronics based on p-type Ge2Sb2Te5 and n-type InGaZnO4 semiconductors

Ultra-thin p-type chalcogenide glass Ge2Sb2Te5 (GST) semiconductor layers are employed to form flexible thin-film transistors (TFTs). For the first time, TFTs based on GST show saturating output characteristics and an ON/OFF ratio up to 388, exceeding present reports by a factor of ~20. The channel current modulation is greatly enhanced by using ultra-thin 5 nm thick amorphous GST layers and 20...

A new solvent polymeric membrane electrode incorporating poly(N-isopropylacrylamide) as a polymer.

Here, we report on a new solvent polymeric membrane electrode incorporating thermoresponsive poly(N-isopropylacrylamide) (PIPA) as a polymer with the lower critical solution temperature (LCST) of ca. 32 °C. The response of the solvent polymeric membrane electrode to the ions changes at 25 and 40 °C. Pulsed NMR analyses demonstrated the novel effects of the LCST behaviour on the potentiometric p...

Highly efficient electrogenerated chemiluminescence of an oligofluorene-truxene star-shaped compound incorporating 2,1,3-benzothiadiazole units

Electrogenerated chemiluminescence (ECL) involves a unique type of electron transfer that generates excited states, namely by the reaction of radical ions. When these excited states relax to a lower-level state, the emission of a photon is detected at a particular wavelength which is determined by the energy gap between the two states. An ECL response by the ion annihilation pathway is achieved...

Supramolecular Luminescence from Oligofluorenol-Based Supramolecular Polymer Semiconductors

Supramolecular luminescence stems from non-covalent exciton behaviors of active π-segments in supramolecular entities or aggregates via intermolecular forces. Herein, a π-conjugated oligofluorenol, containing self-complementary double hydrogen bonds, was synthesized using Suzuki coupling as a supramolecular semiconductor. Terfluorenol-based random supramolecular polymers were confirmed via conc...
