Ahead of his participation at the 2019 OLEDs World Summit, we spoke with Mike Molaire, Founder and CEO of Molecular Glasses, to learn more about his recent advancements in OLED materials and the potential benefits of super soluble noncrystallizable small molecules for both vacuum deposited and printed OLEDs.
Mike, can you share with us how Molecular Glasses came to be and what role you play in the OLED industry?
Molecular Glasses was conceived in 2013 with the filing of six provisional patent applications based on a novel idea for a new class of OLED materials. In 2014 the six provisional applications were converted into four U.S. and PCT applications. To date, four U.S. patents have been issued with the PCT applications pending.
Incorporated in 2015, Molecular Glasses has offices and laboratories in the Eastman Business Park in Rochester, New York. We currently have seven employees and we are fully engaged with the industry, validating our technology toward commercialization.
What innovations do you hope to see in OLED technology over the next few years and how are you working toward achieving them?
I would like to see blue and green TADF, and inkjet-printed OLEDs implemented in the marketplace. We are developing new TADF hosts for both colors that will increase OLED lifetime. Our small molecule materials are very soluble in the solvents used for ink formulation at concentrations above 15%. The high solubility will enable a decrease in the number of printed dots per pixel for large gains in printed OLED productivity. We have also developed a technology to “booster” OLED light emission efficiency.
What problems in the OLED industry does Molecular Glasses see their OLEDIQ™ technology providing a solution to?
Molecular Glasses has developed a unique, patented class of small molecule OLED materials which are highly soluble and non-crystallizable: OLEDIQ™. These properties will allow OEMs to make displays that utilize 40% less power while increasing light output by 30%, device lifetime by 100%, and manufacturing yields by 15%.
Importantly, our materials can be used in both the existing thermal deposition and emerging low-cost solution printing manufacturing processes, thereby enabling the mass market adoption of OLED TVs and other large format displays.
Why do you think the OLEDs World Summit is important, particularly to companies like yours?
The OLEDs World Summit brings together worldwide OLED decision makers in an intimate setting that promotes efficient dialogue, information sharing, and meaningful relationships. This is especially important for startup companies like us. Being able to meet with all the important decision makers, under one roof, in a relaxed atmosphere, is priceless.
Your presentation is titled “Super Soluble Noncrystallizable Small Molecules for Vacuum Deposited and Printed OLEDs” can you tell us why you felt this topic should be shared with the OLEDs World Summit audience?
Imagine a class of materials with the following highly desirable characteristics:
- Forever stable amorphous phase
- Highly soluble in green solvents at concentrations above 10%
- Never crystallizes no matter what the conditions
- Has good charge transport characteristics
- Can dissolve emitters at very high concentration
These same materials can be vacuum-deposited or solution coated (printed) for display, lighting, automotive, and other commercial applications. These materials are Molecular Glasses OLEDIQ™, “Super Soluble Noncrystallizable Small Molecules for Vacuum Deposited and Printed OLEDs”. The OLED community deserves to know about these materials!
Hear more from Mike and Molecular Glasses during his presentation Super Soluble Noncrystallizable Small Molecules for Vacuum Deposited and Printed OLEDs, taking place on Day 2 of the conference (September 26) at 2:30 PM.
