چکیده
New anthraquinone derivatives were prepared and used as active layers of organic field-effect transistors (OFETs); these devices showed good n-type characteristics and the quinones were found to be useful for organic semiconductors in OFETs.

Polyvinylpyrrolidone / Nickel oxide (PVP/NiO) dielectrics were fabricated with sol-gel method using 0.2 g of PVP at different working temperatures of 80, 150 and 200 ºC. Structural properties and surface morphology of the hybrid films were investigated by X- Ray diffraction (XRD) and Scanning Electron Microscope (SEM) respectively. Energy dispersive X-ray spec...
متن کاملOrganic Thin Film Transistors based Oligothiophine Derivatives using DZ-Dihexyl(quarter- and sexi-)Thiophene
End-substitution of quarterthiophene and sexithiophene with hexyl groups leads to highly soluble conjugated oligomers, -dihexylquarterthiophene (DH-4T) and -dihexylsexithiophene (DH-6T). We have characterized these oligomers for optical and electrical properties. We fabricated an organic thin film transistor (OTFT) using the above two air-stable p-type organic semiconductor materials. We obtain...

متن کاملSoluble n-type pentacene derivatives as novel acceptors for organic solar cells†
6,13-Bis(triisopropylsilylethynyl) (TIPS)-pentacene has proven to be a promising soluble p-type material for organic thin film transistors as well as for photovoltaics. In this work, we show that adding electron-withdrawing nitrile functional groups to TIPS-pentacene turns it into an n-type material, which can be used as an acceptor for organic solar cells. Several new cyanopentacenes with diff...
متن کاملMolecular order of air-stable p-type Organic Thin-Film Transistors by tuning the extension of the π-conjugated core: the cases of Indolo[3,2- b]carbazole and Triindole semiconductors
Charge transport in organic devices depends strongly on the molecular order and morphology of the organic semiconductor thin films. In the design of new organic semiconductors, the selection of the appropriate core plays a key role in the molecular packing and charge transport characteristics of the organic device. Four derivatives of carbazole that mainly differ in the extension of the π-conju...
