The most stable of the small pi-conjugated molecular devices fabricated to date are green LEDs based on materials developed at Kodak and now licensed to Pioneer. Generally, you could make gigantic devices. If you wish, you could make a display where each segment is one meter square because fabrication of the device per unit area would be very cheap. Upscaling would be relatively much less of a problem than in any inorganic material, and because polymers are inherently flexible, they can be used to manufacture flexible LEDs. Even if scientists overcome the stability problem, they must still solve the problem of how to increase luminescence in pi-conjugated polymers.
Magnetic resonance is a phenomenon exhibited by the nuclear or electronic magnetic moments.
Within the last few years, interest in ODMR for physical systems has caught on among other research groups. So now there are about three or four groups in the world doing ODMR on polymers and organics. Proponents of ODMR include Richard Friend, Cavendish Professor at Cambridge University in England. The information it provides will enable us to synthesize new materials that will weaken the nonradiative processes and, consequently, enhance the radiative decay needed to produce light. Shedding Some Light on Decay Running ODMR experiments on different pi-conjugated polymers is the job of Ames Lab postdoctoral fellow Jonathan Partee and graduate student Brian Uhlhorn.
