Ohio Patent of the Month – March 2024

Promerus, LLC, an Ohio-based advanced material solutions company, has made a name for itself by developing technologies for the next generation of semiconductors, optoelectronics, and electronic packaging. Recently, the company secured a patent for their new material composition – a UV active derivative for optical materials.

Traditional Organic Light Emitting Diodes (OLEDs) suffer from photon loss as a result of refractive index mismatch between organic layers and substrates. Promerus addresses this with compositions that match the refractive index of organic layers, enhancing light extraction into substrates by 80-90%. Additionally, the invention tackles OLED sensitivity to environmental conditions by offering stable compositions resistant to moisture, oxygen, and temperature fluctuations.

Previous solutions involved multi-component systems or unstable compounds. Promerus’ invention provides a single-component composition capable of mass polymerization upon exposure to actinic radiation. This enables the fabrication of OLED devices with unmatched properties: high refractive index, transparency, and compatibility with OLED stacks. Moreover, the compositions ensure uniform coating, low viscosity, and minimal shrinkage.

The advantages extend beyond OLEDs. Promerus’ compositions find applications in 3D printing, ink-jettable coatings, and sealants. They offer convenience and efficiency, especially in processes like “one drop fill” (ODF) for top emission OLED devices. The single-component nature simplifies fabrication, overcoming limitations of two-component systems.

The invention comprises olefinic monomers, organopalladium compounds, photoacid generators, and photosensitizers. These components, when combined, form compositions capable of producing transparent films and other three-dimensional objects.

Promerus’ invention revolutionizes opto-electronic applications by providing stable, high-performance compositions with a single-component solution. With its ability to address longstanding challenges in OLED fabrication and its versatility across various applications, this innovation marks a significant leap forward in the field of opto-electronics.
