Organic semiconductors (OSCs), based on pi-conjugated molecules and macromolecules, are revolutionising the electronics industry. OSCs offer several key characteristics that can be used to provide major advantages over silicon based devices. OSCs can be made by cheap solution deposition techniques such as spin-coating, roll-to-roll processing and ink-jet and screen printing. Polymer based OSCs can be used to provide flexible devices and this, coupled with the fact that OSCs function effectively as thin films (ca. a few hundred nm thickness), means that the devices are lightweight, highly portable, extremely fashionable and exceptionally marketable.
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). OLEDs have already reached the market and our understanding of structure-property relationships and photophysics in this field are already well established. In the case of OPVs and OFETs, the major challenge is to match the performance of amorphous silicon in analogous devices.
The emerging areas of molecular and bioelectronics and lasing should also see considerable growth over the next few years. 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 around the theme of organic electronics and photonics. It will bring together experts in chemistry, physics, biology and electronic engineering and thereby provide a multidisciplinary platform for debating current and future work in organic electronics.
The Discussion will focus on four specific topics over the half-day sessions: organic photovoltaics and energy, organic lasers, bioelectronics and sensors and molecular electronics. The Discussion will appeal to a wide range of scientists and will collectively represent the most exciting developments in organic electronics research.
