Air Products and the University of Connecticut today announced an exclusive licensing agreement under which Air Products may develop and market materials covered by the University's recently issued United States patent 7,071,289 entitled "Polymers Comprising Thieno [3,4-B] Thiophene and Methods of Making and Using the Same." The technology will help increase the lifetime of Polymer Light Emitting Diodes (P-OLEDs) for displays.
Building on the fundamental invention of poly (thieno [3,4-b] thiophene) by Professor Gregory Sotzing at the University of Connecticut, and dopant polymer technology by Air Products, the two institutions have developed Hole Injection Layer (HIL) materials for P-OLEDs which provide a dramatic increase in display lifetime compared to conventional HIL materials, without need for a costly protective interlayer.
