SUMMARY:Conférence CRMAA avec le professeur Klaus Meerholz (Cologne)
DESCRIPTION:Titre : Crosslinkable semiconductors for use in solution-proces
 sed organic light-emitting diodes (OLED).Cette conférence sera prononcé
 e par le professeur Klaus Meerholz du département de chimie de l'Univers
 ité de Cologne. Elle est commanditée par le Centre de recherche sur les 
 materiaux auto-assemblés (CRMAA) et sera donnée en anglais.Résumé : 
 Organic light emitting diodes (OLEDs) based on electroluminescent conjugat
 ed polymers are considered a promising alternative for display and lightin
 g applications\, mainly due to their better compatibility with low-cost pr
 oduction techniques and large substrates. A challenge is multiple-layer de
 position to improve the efficiency of the devices and\, as a result\, thei
 r lifetime. We have in the past developed photochemically crosslinkable se
 miconductors for fabrication of complex multilayer OLED and lithographic R
 GB-pixelation down to the micron scale. Grey- scale lithographic capabilit
 y has been demonstrated\, allowing the fabrication of multiple cavities wi
 th different lengths in a single processing step and thus permits monolith
 ic integration of multiple OLEDs with different emission wavelengths on a 
 single substrate. By use of nanoporous hole-injection layers improved outc
 oupling has been demonstrated. Recently\, we demonstrated a surface-initia
 ted crosslinking process with high potentials in printing and 3D- coatings
 . After curing the materials feature excellent thermal robustness\, allowi
 ng to process on top even elevated temperatures (e.g. up to 200C).Informat
