Studies from University of Toronto Reveal New Findings on Optoelectronics (Selenophene Electronics)

August 6, 2014

By a News Reporter-Staff News Editor at Electronics Newsweekly -- Data detailed on Optoelectronics have been presented. According to news originating from Toronto, Canada, by VerticalNews correspondents, research stated, "Substituting individual heavier (or lighter) atoms would appear to be an extremely straightforward method of controlling the optoelectronic properties of pi-conjugated molecules that has minimal impact on solid-state materials properties, yet things are never as they appear. Selenophenes are a distinct class of material separate from thiophenes."

Our news journalists obtained a quote from the research from the University of Toronto, "Their HOMO-LUMO gap is often narrow, which is attractive for photonic applications. Intermolecular Se-Se interactions increase ordering on a molecular scale and lead to distinct solid-state organization, which often leads to excellent charge-transport properties. The crystallization of selenophene is distinct from thiophenes, and thus, composites of selenophenes and other organic materials have distinct nano-and microscale morphologies. Some of the best organic optoelectronic devices use selenophene-containing materials, yet early results were less encouraging. The most recent syntheses, structure determination, and electronic device properties of pi-conjugated selenophene-based materials are reviewed."

According to the news editors, the research concluded: "Significantly more work is justified and this review sets the stage for those studies."
