Ruthenium Bipyridine Wafer
A pair of tweezers holds a ruthenium bipyridine wafer. The wafer will serve as the base for six efficient, single layer, solid-state light-emitting devices (one of the devices is lit). These devices are being developed for applications in flat panel displays and lighting.
Work in the Malliaras Group (device fabrication and studies) was funded by National Science Foundation Faculty Early Career Development (CAREER) Program (award DMR 00-94047). The synthesis of the materials took place in the Abruna Group and was funded by the Cornell Center for Materials Research (CCMR), an NSF Materials Research Science and Engineering Center (MRSEC) (grant DMR 96-32275).

More about this Image
Once the target of solely experimental research, the electronic and photonic components that are crafted from organic chemicals now drive major markets. Uses for the scalable, light weight technologies range from the billion dollar photo-conductive film industry to the growing market for solid-state lighting, such as LEDs (light-emitting diodes).
Organic electronic and photonic applications that are still in development may have an even broader impact, serving as flexible electronics, biologically-compatible devices, solid-state lighting and chemical sensors, as well as devices yet to be conceived.
In January 2003, an NSF-sponsored workshop took place in which experts from industry and universities came together to discuss the future of the field. Some of the highlights discussed by participants were new developments, changing directions in research and the needs facing investigators as they train the next generation of engineers.
