DuPont Displays today announced it has developed a new, proprietary third generation (Gen 3) solution-based organic light emitting diode (OLED) materials technology, which has led to substantial performance gains for printable OLED light-emitting materials. A DuPont Gen 3 green OLED material achieved a record lifetime of over 1,000,000 hours, while two new Gen 3 solution blue materials have been developed that set new standards for longevity and color. Gen 3 OLED materials can meet or exceed the performance of todays vapor deposited materials, and are paving the way for lower cost solution process OLED displays.

For over 40 years, bisphenol A labored in relative obscurity as the feedstock for a wide range of commercial plastics and synthetic resins. Growing demand for polycarbonates—for products ranging from baby bottles to compact discs—drives the rapidly expanding multibillion-dollar market for bisphenol A, one of the highest-volume chemicals in commercial production [see related essay (published online 17 July 2007); doi:10.1371/journal.pbio.0050200]. Bisphenol A molecules, which are joined by unstable bonds to form polycarbonates and resins, leach from containers exposed to heat or highly acidic or basic compounds. Although bisphenol A's estrogenic activity was first reported in 1936, scientific interest in the chemical has recently increased along with evidence of its effects. And as the media increasingly cover these findings, the chemical industry has stepped up its attacks on those studying endocrine disruption.
