Organic semiconductors (OSCs), based on pi-conjugated molecules and macromolecules, are revolutionising the electronics industry. The most topical and potentially lucrative applications to date include organic light emitting diode (OLED) displays and lighting, organic photovoltaics (OPVs) and organic field effect transistors (OFETs). Applications for these technologies are varied and include sensing, medical diagnostics, artificial assemblies, computing and information and communication technologies. This discussion encompasses a range of topical subjects, centred on the theme of organic electronics and photonics, focussing on four specific topics: organic photovoltaics and energy, organic lasers, bioelectronics and sensors and molecular electronics, representing the most exciting developments in organic electronics research.
