In the last ten years the Laboratory of Optoelecronics of Molecular Materials (LOMM) has built a broad experimental and theoretical expertise in the field of organic thin film devices such as organic light emitting diodes (OLEDs) and organic field effect transistors (OFETs).

An extensive research program on OLEDs allowed the development of appropriate optical techniques. Some of them were standard, such as optical absorption, fluorescence, photoluminescence or colorimetry; others, such as electroabsorption or internal photoemission, were more specific. Using these tools the LOMM could study light emitting polymer nanostructures, multilayer devices based on carbazole dyes, the role of injection layers, and the role of the dopant molecules on light emission.

The research has also been focused on the use of self-assembled monolayers (SAMs) of organic molecules as interfaces in OFET and OLED devices, and on the fundamental understanding of charge transport and charge injection in molecular materials and devices.

Recently, research efforts have been directed towards the infiltration of photonic crystal structures (PhCs) with optically active molecules, and on the study of functional organic-inorganic hybrid multilayers for photonics, optics and imaging applications. In the latter field, the LOMM has launched since 2005 an EPFL-Project, the Laboratory of Optical Thin Films and Imaging (LOTFI), in collaboration with ILFORD Imaging Switzerland GmbH, located in Marly (Switzerland). The commitment of the two partners converges into an attempt of establishing a new and unique form of collaboration for innovation and technology transfer between a Swiss academic institution and a Swiss industry.
