Journal ArticleDOI
RF Tag Antenna Performance on Various Materials Using Radio Link Budgets
TL;DR: This paper presents two new useful forms of the radio link budget that describe the power link of an RF tag system when the tag is attached to an object and quantifies the reduction in RF tag antenna gain due to material attachment.
Journal ArticleDOI
Norbornene-based copolymers with iridium complexes and bis(carbazolyl)fluorene groups in their side-chains and their use in light-emitting diodes
Alpay Kimyonok,Benoit Domercq,Andreas Haldi,Jian Yang Cho,Joseph R. Carlise,Xian Yong Wang,Lauren E. Hayden,Simon C. Jones,Stephen Barlow,Seth R. Marder,Bernard Kippelen,Marcus Weck +11 more
TL;DR: In this article, solution-processable copolymers with pendant phosphorescent iridium complexes and 2,7-di(carbazol-9-yl)fluorene-type host moieties were synthesized using ruthenium-catalyzed ring-opening metathesis polymerization.
Journal ArticleDOI
Optimization of Orange‐Emitting Electrophosphorescent Copolymers for Organic Light‐Emitting Diodes
Andreas Haldi,Alpay Kimyonok,Benoit Domercq,Lauren E. Hayden,Simon C. Jones,Seth R. Marder,Marcus Weck,Marcus Weck,Bernard Kippelen +8 more
TL;DR: In this paper, the efficiency of multilayer organic light-emitting diodes (OLEDs) was optimized by varying characteristics of the copolymers: the molecular weight, the iridium loading level, and the nature and length of the linker between the side chains and the polymer backbone.
Journal ArticleDOI
Effects of surface modification of indium tin oxide electrodes on the performance of molecular multilayer organic photovoltaic devices
Asha Sharma,Andreas Haldi,William J. Potscavage,Peter J. Hotchkiss,Seth R. Marder,Bernard Kippelen +5 more
TL;DR: In this article, the effects of surface modification of indium tin oxide (ITO) on the performance of organic multilayer molecular photovoltaic devices based on pentacene/C60 bi-layer heterojunctions were investigated.
Journal ArticleDOI
Fluorenyl-substituted silole molecules: geometric, electronic, optical, and device properties
Xiaowei Zhan,Xiaowei Zhan,Andreas Haldi,Chad Risko,Calvin K. Chan,Wei Zhao,Tatiana V. Timofeeva,Aleksander Korlyukov,Mikhail Yu. Antipin,Sarah Montgomery,Evans Thompson,Zesheng An,Benoit Domercq,Stephen Barlow,Antoine Kahn,Bernard Kippelen,Jean-Luc Brédas,Seth R. Marder +17 more
TL;DR: In this paper, the effect of substitution pattern on the geometric, thermal, electronic, optical, and electroluminescence properties of a series of silole molecules with fluorenyl substituents at varying positions was investigated both experimentally and theoretically.
