| :: Light Sources and Organic Electronics - Description |
| |
This thrust focuses on light-emission and charge transport in organic and hybrid materials. New materials with tailored molecular architecture under development include dendrimers, self-assembled mesophases, and crystals processed by physical vapor deposition. The approach is to fine tune molecular orbital energies, to minimize reorganization energy, and optimize intermolecular coupling in assemblies to obtain high charge mobility, to take advantage of site isolation in dendrimers to control energy transfer processes, and to control light-emission at the molecular level. These materials will be processed at low temperature and inserted into devices on shatterproof flexible plastic substrates using low cost printing and soft lithography techniques. The objectives are to develop:
- new light-sources for telecommunications,
- photopatternable organic light-emitting displays, and
- stable high-mobility organic materials, and to incorporate them into electronic devices.
