Organic Light Emitting Diode Technology (OLED) is poised to challenge Light Emitting Diode (LED) and Liquid Crystal Display (LCD) in flat panel displays, flexible displays, and lighting applications. OLED display has an advantage over LCD with its high response speed, wide viewing angle, and high contrast in dark settings. There are, however, two major challenges slowing down OLED: production costs must decrease and device longevity needs to improve.1, 2, and 3This presentation will introduce a new class of noncrystallizable charge transporting and/or electroluminescent materials designed to improve device stability and efficiency. We will report on the design, synthesis, and characterization of noncrystallizable electron-transporting, hole-transporting, bipolar charge-transporting, and luminescent small molecule materials. The concept behind this class of compounds and the reasons for their efficacy will be discussed.Traditional thermal OLED production is too expensive. Solution processes for spin, roll-to-roll, slot die, or inkjet coating are required. The traditional small molecules used for thermal deposition tend to crystallize in solvents. OLED systems using polymeric materials (PLED) are being developed. Polymeric charge transport materials tend to have relatively low transport properties. Recently, there have been a lot of activities surrounding “molecular glasses” for solution smOLED processes (small molecules OLED).4 These molecular glasses are defined as “amorphous materials in the state of thermo;dynamic nonequilibrium, and hence, they tend to undergo structural relaxation, exhibiting well-defined glass temperature Tg's. However they also tend to crystallize on heating above their Tg's, frequently exhibiting polymorphism”.5, 6 With time, equilibrium will lead to crystallization of these materials. When that happens, the performance of the device is degraded, limiting longevity. An additional problem with current small molecule OLED materials is their solubility. Either solubility is limited or requires non-green solvents.Molecular Glasses, a division of Molaire Consulting LLC, is developing a new class of truly noncrystallizable amorphous small molecule organic electronics materials with high solubility in various green solvents.7 This new class of amorphous small molecule OLED materials is defined as mixtures of compatible molecules with an infinitely low crystallization rate under the most favorable conditions. They are essentially noncrystallizable with a large entropy of mixing values amenable to compatibility with a wide range of materials at a very high concentration.
