Organic semiconductors continue to draw great attention from different disciplines because of the plethora of unique and attractive properties they can exhibit. Recent advances in fundamental understanding, coupled with the introduction of new materials and synthetic routes, have enabled the development of a wide range of devices with new functionalities and performance on par with established inorganic technologies. Such demonstrations are paving the way for many innovative applications in emerging sectors of science and technology. This symposium focuses on recent advances on the synthesis, characterization and application of organic materials and devices. Of particular interest are the molecular design, solid-state structure, physics and applications of emerging classes of molecules, including macromolecular semiconductors, molecular dopants, self-assembling surface-modifying molecules, open-shell organic semiconductors, light-emitting molecules with enhanced reverse intersystem crossing, solid-state laser materials, organic thermoelectrics and mixed ion-electron (hole) conductors. The ultimate aim of the symposium is to provide a venue for researchers to discuss recent developments, challenges and emerging opportunities in this field.
