Air Products licenses OLED materials

August 14, 2006 | A version of this story appeared in Volume 84, Issue 33

Air Products & Chemicals has signed a licensing agreement with the University of Connecticut for the further development of materials that were invented by associate professor of chemistry Gregory Sotzing and are based on poly(thieno[3,4-b]thiophene). The materials are used in an organic light-emitting diode's hole injection layer, which supplies the light-emitting polymer with a positive charge that an electron can combine with to create light. The company says the technology will help increase the lifetime of OLEDs and will eliminate the need to apply costly protective layers to the hole injection layer.
