TL;DR: In this paper, a field effect transistor (FET) based on poly(3-n-hexylthiophene) was investigated to determine the influence of moisture on device characteristics and gain a deep understanding of the mechanism underlying the susceptibility to air of the operation of FETs of this kind.
Journal ArticleDOI
Energy transfer and device performance in phosphorescent dye doped polymer light emitting diodes
TL;DR: Singlet and triplet-triplet energy transfer in phosphorescent dye doped polymer light emitting devices were investigated in this article, where the host poly(N-vinylcarbazol) and poly[9,9′-di-n-hexyl-2,7-fluorene-alt- 1,4-(2,5-di)-nhexyloxy)phenylene] (PFHP) were selected as the host polymer for the phosphorescent dopants fac-tris(2-phenylpyridine) iridium(III) [
Journal ArticleDOI
Dicarboxylic Oligopeptide Bolaamphiphiles: Proton-Triggered Self-Assembly of Microtubes with Loose Solid Surfaces
TL;DR: A new family of oligopeptide-based bolaamphiphiles with a dicarboxylic headgroup at each end has been synthesized in this paper, which can be linked via amide bond to a long-chain α,ω-dicar boxylic acid as a hydrocarbon spacer.
Journal ArticleDOI
Highly sensitive thin-film organic phototransistors: Effect of wavelength of light source on device performance
TL;DR: In this paper, a high performance OFET with pentacene and copper phthalocyanine (CuPC) was fabricated from organic phototransistors (OPTs) based on the geometry of organic field effect transistors (OFETs); and the effect of the wavelength of the incident light source on their performance was examined.
