Electron Trap Dynamics in Polymer Light-Emitting Diodes

Frank Nüesch, Roland Hany, Michael Bauer, Matthias Diethelm, Wei-Hsu Hu

Semiconducting polymers are being studied intensively for optoelectronic device applications, including solution-processed light-emitting diodes (PLEDs). Charge traps in polymers limit the charge transport and thus the PLED efficiency. It is firmly establi ...

Mechanistic Study of Diaryl Ether Bond Cleavage during Palladium-Catalyzed Lignin Hydrogenolysis

Jeremy Luterbacher, Yuan Li

Hydrogenolysis has emerged as one of the most effective means of converting polymeric lignin into monoaromatic fragments of value. Reported yields may be higher than for other methods and can exceed the theoretical yields estimated from measures of the con ...
