Semiconducting  organic  materials  have  been  the  focus  of  attention  of  materials  scientist  and  engineers over  the  last  two  decades.  Tailoring  the  molecular  and  supramolecular  structure  of  organic  materials allows  the  manipulation  of  their  mechanical,  electrical  and  optoelectronic  properties  with  elegance, precision,  and  endless  versatility,  thus  improving  the  existing  technologies  and  enabling  novel applications.  Organic  light- emitting  diodes  (OLED),  field- effect  transistors  (OFET),  photovoltaic  cells (OPV,  DSSC  and  perovskites  (hybrid  nanostructures))  and  conjugated  polymer  sensors  are  aggressively entering  the  market,  whilst  other  technologies  are emerging and rapidly developing (e.g. organic lasers and materials for  LiFi).

Recent progress in the synthesis of new materials led to excellent performance for OFET devices with charge-carrier mobilities above 10 cm2/Vs being reported; while power conversion efficiencies above 12 % have been demonstrated with OPVs, around 15 % for DSSC and over 22 % for perovskite solar cells. While further progress in molecular design is certainly possible and necessary, there is a growing understanding in the field that the “supramolecular control” of molecular packing and materials morphology is necessary to realize the full potential of organic electronics.

Photonics research is a highly complementary theme to organic electronics and, indeed, integrated in many applications. The 21st century will depend as much on photonics as the 20th century depended on electronics. Photonics products are everywhere, in consumer electronics (barcode scanners, DVD players), telecommunications (internet), health (eye surgery, medical instruments, diagnostics), the manufacturing industry (laser cutting and machining), defense and security (infrared camera, remote sensing), entertainment (holography, laser shows), etc. Most photonic applications are in the range of visible and near-infrared light. For these, organic materials start to play a crucial role.

This symposium will focus on an interdisciplinary approach where chemistry, physics and material engineering are combined to address the fundamental and practical aspects of organic optoelectronic materials and their integration in electronic and photonic devices.
