Molecular Glasses™ Files Patents on Crosslinkable and NONcrystallizable™ Organic Semiconductors for OLED and other Organic Electronics: “NONcrystallizable™ OLED”
ROCHESTER, New York, January 6 — Molecular Glasses, a division of Molaire Consulting LLC, has filed for patent protection for its crosslinkable and non-crystallizable organic semiconductor materials for OLED and other organic electronic applications.
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 crosslinkable and non-crystallizable hole-transporting, electron-transporting, ambipolar and luminescent compositions of matter, including procedures to ensure their purity. Also covered is a process of printing dopants image-wise on the surface of a host material plasticized with a very low-glass-transition-temperature (Tg) crosslinkable multifunctional material. The lower-Tg composition enables subsequent thermal diffusion of the dopants into the host layer uniformly at a very low temperature (below 80° C) without the assistance of solvent. Once dopant diffusion is completed, the layer is exposed to actinic energy for crosslinking and restoration of its original thermal properties.
Organic light emitting diode (OLED) is poised to challenge light emitting diode (LED) and liquid crystal (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. However, two major challenges are slowing down OLED:
1. Production costs must decrease. Traditional thermal OLED production is too expensive. 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 crystallize in solvents.
2. NONcrystallizable™ molecular glasses are soluble in various coating solvents and can be coated using roll-to-roll coating processes. However, it is not practical to coat many layers without damaging the previously coated layers, unless a solvent barrier layer is utilized. Or it is required to carefully engineer the solubility of each layer. For example, the solvent of the second coated layer cannot dissolve the first coated layer; the solvent of the third coated layer cannot dissolve the second coated layer and so on.
We have developed our novel crosslinkable and non-crystallizable materials to address these problems. Our crosslinkable and NONcrystallizable™ OLED materials will bring OLED display manufacturing costs to levels lower than that of LCD displays by enabling solution processing. It is projected that solution processing will reduce manufacturing costs of a 55 in. OLED display by 44.4% compared to the traditional thermal evaporation process. In addition, Molecular Glasses’ crosslinkable and NONcrystallizable™ organic semiconductors will provide the industry many new benefits:
1. Easily tuned charge-transporting properties for balanced electron and hole transport resulting in highly efficient devices
2. Reduced emitter aggregation for higher internal conversion
3. Increased dopant concentration in compatible and noncrystallizable hosts for longer-live devices
4. Dual solvent and vacuum coatability for manufacturing flexibility
5. Green solvent solubility to protect the environment
6. Efficient single layer devices for lower cost
“We are very excited about these new features of our technology,” notes Mike Molaire, CEO and Founder of Molecular Glasses. “The ability to crosslink our materials will simplify the fabrication process. Our crosslinkable plasticized-host materials further simplify the fabrication process by enabling low temperature diffusion of image-wise-printed blue, red, and green dopants without assistance of solvent for the production of large-size-full-color displays.
“There are two recognized classes of OLED materials today: ‘Small Molecule OLED’ and ‘Polymer OLED.’ We have invented a third class: ‘NONcrystallizable™ OLED’ capable of providing all the advantages of the others and more.
NONcrystallizable™ means Efficient OLED. Long-lived OLED. Affordable OLED.
“We are building a strong patent portfolio and looking for strong partners to bring the technology to market in a reasonable time.”
