Molecular Glasses announces novel organic semiconductors

These amorphous small molecule materials are mixtures of compatible molecules with an infinitely low crystallisation rate - suitable for OLED and organic electronics

2 Oct 2014 | Editor

Molecular Glasses, a division of Molaire Consulting, has announced they have developed a novel class of organic semiconductor materials suitable for OLED and other organic electronic devices. These new materials are a class of truly noncrystallizable amorphous small molecule organic electronics materials with high solubility in various green solvents. This new class of amorphous small molecule OLED materials are defined as mixtures of compatible molecules with an infinitely low crystallization rate under the most favourable conditions. They are essentially noncrystallizable with large entropy of mixing values amenable to compatibility with a wide range of materials at very high concentration.

According to Molecular Glasses OLED technology is poised to challenge both LCD and LED technologies in flat panel displays, flexible displays and lighting applications. OLED displays are widely promoted as having an advantage over LCD due to their high response speed, wide viewing angle and high contrast. However two major challenges are slowing down OLED.

  • Production costs must decrease
  • Device longevity needs to improve

Traditional thermal OLED production is too expensive, and solution processes for spin, roll-to-roll, slot die, or inkjet coating are required. However the traditional small molecules used for thermal deposition tend to crystallise in solvents.

Molecular Glasses believe their novel noncrystallisable materials to address these short-comings. The company believes that their "NONcrystallizable" OLED materials will bring OLED display manufacturing cost to levels lower than that of LCD displays by enabling solution processing. It is projected that solution processing will reduce manufacturing cost of a 55” OLED display by 44.4% compared to the traditional thermal evaporation process. In addition Molecular Glasses’ "NONcrystallizable" organic semiconductors will provide the industry with a range of new benefits:

  • Easily tuned charge-transporting properties for balanced electron and hole transport resulting in highly efficient devices
  • Reduced emitter aggregation for higher internal conversion
  • Increased dopant concentration in compatible and noncrystallizable hosts for longer-live devices
  • Dual Solvent and vacuum coatability for manufacturing flexibility
  • Green solvent solubility to protect the environment
  • Efficient single layer devices for lower cost

The company has filed for patent protection for its new class of organic semiconductor materials. The filing converts prior provisional applications into full U.S. and PCT patent filings, but also incorporates additional proprietary aspects of the Company’s material and process that were recently developed.

The new patent filings cover the preparation of novel noncrystallizable hole-transporting, electron-transporting, ambipolar, and luminescent composition of matter, including procedures to ensure their purity.
