Latest Patents

One of Rohwer's latest patents is titled "Tunable rare earth metal-organic frameworks for complex optical tags." This invention provides a powerful design strategy for next-generation, multiplexed, lifetime-encoded tags. It achieves this by engineering intermetallic energy transfer in heterometallic metal-organic frameworks based on nonanuclear metal clusters. The invention allows for precise manipulation of luminescence decay dynamics over a wide microsecond regime, thanks to the control over metal ordering in these systems. A notable application of this invention is a novel, dynamic double encoding method that utilizes the braille alphabet. This method incorporates the materials into photocurable inks patterned on glass and is interrogated via digital high-speed imaging. The facile synthesis and interrogation of these heterometallic metal-organic frameworks, which possess complex and tunable optical properties, enable the creation of next-generation, multiplexed optical tags.

Another significant patent is focused on "Optical tags comprising rare earth metal-organic frameworks." This invention addresses the need for quick and unambiguous asset identification, which is crucial for anti-counterfeiting and the protection of valuable resources or information. The patent describes a tag fluorophore that encodes multilayer complexity in a family of heterometallic rare-earth metal-organic frameworks (RE-MOFs). These frameworks are based on highly connected polynuclear clusters and carboxylic acid-based linkers. The optical tags exhibit both overt (visible) and covert (near infrared, NIR) properties, along with multi-emissive spectra and tunable luminescence lifetimes. This complexity enhances security and allows for tag authentication through various orthogonal detection methodologies. The relationships between structure, composition, and optical properties of the RE-MOFs can be utilized to create a large library of rationally designed, highly complex, and difficult-to-counterfeit optical tags.
