This report reveals utilization of phase transitions and corresponding changes in physical properties of organic semiconductors for implementing reconfigurable organic optoelectronic devices, i.e., a device whose configurations and characteristics can be programed after fabrication. Specifically, glass transitions of amorphous molecular materials have been exploited to demonstrate reconfigurable organic light-emitting devices (OLEDs) capable of generating any of the three primary colors. The capability to pattern such devices into fine color pixels with thermal imaging renders it attractive for applications in high-resolution full-color OLED displays and as active optical memory devices.
