New Materials for High-Efficiency Organic Light-Emitting Devices (OLEDs) and Solid-State Lighting (SSL)

Fluorescent and phosphorescent organic/organometallic materials are receiving intense interest as emitters in electroluminescent organic light-emitting diodes (OLEDs) for displays and solid-state lighting (SSL).

The background concepts will be briefly described before a presentation of recent work in the Durham labs. Topics will include the design, synthesis, photophysical properties and OLED performance of fluorescent copolymers, and phosphorescent Ir(III) complexes. Color tuning of emission, including efficient white light emission will be reported.

Phosphorescent device efficiencies as high as 40 cd/A with external quantum efficiencies of 12% for green emission have been achieved in simple solution-processed device architectures. RSVP

About Martin Bryce

Martin Bryce was born near Birmingham, UK and graduated from Wolverhampton Polytechnic (B.Sc. 1st class). He completed a D.Phil. at York University under the guidance of John Vernon and Peter Hanson in 1978. Following postdoctoral appointments at the University of British Columbia, Vancouver (with Larry Weiler) and the University of Bristol (with Roger Alder) he joined Durham University. He was promoted to Professor of Chemistry in 1995. He is the recipient of the Ciba-Geigy Award for academic collaboration in Europe (1990), the Royal Society of Chemistry Bader Award (1992), the Royal Society of Chemistry Interdisciplinary Award (1992), the Nuffield Foundation Science Research Fellowship (1993), the University of Durham Sir Derman Christopherson Fellowship (1995) and the Royal Society of Chemistry Heterocyclic Chemistry Award (2002). Martin has held Visiting Scientist positions at the University of California, Santa Barbara, and the University of Copenhagen. He was a Troisième Cycle Lecturer at several universities in Switzerland in 2008. Since 1990 he has been the co-director of the Durham University Centre for Molecular and Nanoscale Electronics. He was the Scientific Editor of the Journal of Materials Chemistry (1995-2000). Martin is the coordinator of the EC FP7 Marie Curie ITN “Fundamentals of Molecular Electronic Assemblies” (FUNMOLS) (2008-2012) comprising 10 European partner laboratories.
