ICEL ’10 – 2014 Cologne

Currently, the 10th International Conference on Electroluminescence and Organic Optoelectronics (ICEL ’10) is held in Cologne, Germany (August 31 – September 3, 2014) and I am happy that I decided to attend. The organizers (Klaus Meerholz, Selina Olthof, and Dirk Hertel) have set up a great conference bringing together a critical mass of experts in the field.

Some highlights from Monday and Tuesday: Stephen Forrest reports on improved OLED lifetime (10x) for blue phosphorescence achieved by exciton management; John Lupton summarizes his efforts on using organic molecules to probe singlet and triplet states and highlights some recent results on mapping both excitonic and nuclear spins in optoelectronic devices; Klaus Müllen presents his groups effort on bottom-up approaches to realize graphene nano structures with perfect order through organic synthesis; Mark Thompson shows very interesting results in applying symmetry breaking charge transfer molecules to increase the OPV open circuit voltage.

In general, there is a great representation of both recent efforts on thermally activated delayed fluorescence (TADF) and sophisticated optics for enhanced OLED light outcoupling. The results presented are remarkable. Another topic that got very good attention is emitter dipole orientation – we are seeing the transition from observation to attempt of understanding the effect. For tomorrow, we are expecting a refresh of the work of Chihaya Adachis group in his plenary talk early in the morning (Wednesday).

If you are not here, you should consider coming for the next meeting in two years from now. Following the tradition of alternating continents hosting the conference, the US is expected to host in 2016.
