20_14b/2008Inside Front Cover: Manipulating the Local Light Emission in Organic Light-Emitting Diodes by using Patterned Self-Assembled Monolayers (Adv. Mater. 14/2008)

The inside cover shows an optical micrograph picture of an organic light-emitting diode with patterned, micro-contact-printed self-assembled monolayers (SAMs) that modify the work function of the anode, reported by Simon Mathijssen, Dago de Leeuw, and co-workers on p. 2703. In this particular light-emitting diode a fluorinated alkanethiol has been used that increases the work function and therefore improves the injection of holes. This results in a higher light emission on the positions where the SAM has been printed, which can be observed as the red pattern.
