A Novel Bipolar Electroluminescent Poly(arylene ethynylene) Consisting of Carbazole and Diethynylthiophene Units
TL;DR: In this paper, a bipolar conjugated copolymer poly[(2, 5-diethynylthienylene)-alt-co-(9-hexyl-3,6-carbazole)] (PCT) bearing electron-affinitive moiety of 2,5-dimethyltienylthiophene and hole-transport mixtures of carbazole was synthesized via a Pd-catalyzed coupling reaction.
Journal ArticleDOI

Julie A. Bardecker,Julie A. Bardecker,Ali Afzali,George S. Tulevski,Teresita Ordonez Graham,James B. Hannon,Alex K.-Y. Jen +6 more
TL;DR: In this article, the use of a UV-sensitive self-assembled monolayer photoresist to selectively deposit single-walled carbon nanotubes from solution using heterogeneous surface wettability is reported.
Journal ArticleDOI
Nanorheological approach for characterization of electroluminescent polymer thin films
TL;DR: In this paper, the photoluminescence quantum efficiency of poly(p-phenylenevinylene) (PPV) was directly correlated to the glass transition property by shear-modulated scanning force microscopy (SM-SFM).
Journal ArticleDOI
Molecular mobility in self-assembled dendritic chromophore glasses.
Daniel B. Knorr,Xing-Hua Zhou,Zhengwei Shi,Jingdong Luo,Sei-Hum Jang,Alex K.-Y. Jen,René M. Overney +6 more
TL;DR: In this study, nanoscale thermo-mechanical analyses yield direct insight into the molecular enthalpic and entropic relaxation modes of self-assembling molecular glasses involving dendritic arene stabilization moieties with electro-optical activities above 300 pm/V.
Journal ArticleDOI
Electro-optic properties of hybrid solgel doped with a nonlinear chromophore with large hyperpolarizability.
Hong Xi Zhang,Dong Lu,Nasser Peyghambarian,Mahmoud Fallahi,Jingdong Luo,Bao Quan Chen,Alex K.-Y. Jen +6 more
TL;DR: The electro-optic properties of hybrid silica solgel doped with a nonlinear chromophore with large hyperpolarizability have good temporal stability and show promise for the development of high-speed electro-Optic devices.
