Georgia Tech inventors have developed Coronene diimide-containing materials for use in organic electronics and optoelectronics. Such room-temperature discotic liquid crystalline coronene diimides have a high charge carrier mobility and processability. Moreover, these materials have the capability of stacking into highly order columns, providing the potential to reduce manufacturing costs and enhance performance of organic electronics and optoelectronics.
- Stable — chemical, thermal, and photochemical stability and relatively low carrier mobility
- Cheaper — tunable properties and simple processing methods, combined with the mechanical flexibility make new materials ideal for large-area applications
- Versatile — can be cast on a variety of low cost substrates: glass, plastic, and metal foils
- Large-scale electronic and electro-optic devices
- Organic light emitting diodes (OLED)
- Colored displays
- Field effect transistors (FET)
- Photovoltaic (PV) devices
- Supramolecular architectures
Organic optoelectronics are considered to be a key technology for the 21st century. Organic materials have gained considerable interest as potential active elements, acting as charge-carrier transport/ generation or injection media in electronic and opto-electronic devices due to many advantages over their inorganic counterparts. Perylene and its derivatives are among the most intensively investigated chromophores due to their outstanding chemical, thermal and photochemical stability. Although Coronene has similar photo- and electroluminescence properties (300-550 nm absorption bands), its experimental chemical modifications have been limited. The emissions of new coronene compounds could be utilized for a variety of applications.
