Structural and electronic implications for carrier injection into organic semiconductors

Philippe Bugnon, Mauro Castellani

We report on the structural and electronic interface formation between ITO (indium-tin-oxide) and prototypical organic small molecular semiconductors, i.e., CuPc (copper phthalocyanine) and alpha-NPD (N,N'-di(naphtalen-1-yl)-N,N'-diphenyl-benzidine). In pa ...

An ester-substituted iridium complex for efficient vacuum-processed organic light-emitting diodes

Michael Graetzel, Mohammad Khaja Nazeeruddin, Rosario Scopelliti, Libero Zuppiroli, Philippe Bugnon, Stéphane Suarez

An orange-red-emitting iridium complex (N958) was prepared, and its photophysical and device-based characteristics were investigated. Despite N958 displaying quite poor photophysical properties in solution (acetonitrile), organic light-emitting diode (OLED ...

Sublimation Not an Innocent Technique: A Case of Bis-Cyclometalated Iridium Emitter for OLED

Michael Graetzel, Mohammad Khaja Nazeeruddin, Rosario Scopelliti, Libero Zuppiroli, Philippe Bugnon, Stéphane Suarez

Isomerization of a neutral bis-cyclometalated iridium(III) complex has been observed for the first time during the preparation of vacuum-processed organic light-emitting devices (OLEDs) and reproduced in solution. Isolation of the isomer revealed a cis org ...

Efficient blue light-emitting diodes based on a classical "push-pull" architecture molecule 4,4 prime -di-(2-(2,5- dimethoxyphenyl)ethenyl)-2,2 prime -bipyridine

Michael Graetzel, Mohammad Khaja Nazeeruddin, Libero Zuppiroli, Rosario Scopelliti, Philippe Bugnon, Detlef Berner, Filippo de Angelis, Mauro Castellani

A novel, highly blue luminescent molecule containing donor and acceptor groups, 4,4 prime -di-(2-(2,5-dimethoxyphenyl)ethenyl)-2,2 prime -bipyridine, that shows photoluminescence emission at 450 nm with 43% quantum yield is designed and synthesized. Time d ...
