Universal Display Corp Organic Electroluminescent Compound Patent Application
Summary
Universal Display Corporation filed patent application US20260114182A1 on April 23, 2026, covering a compound of Formula I for organic electroluminescent materials and devices. The application claims compounds with a 5-membered or 6-membered aromatic ring, where at least one of X1 to X3 is nitrogen, with substituents including alkyl, cycloalkyl, aryl, heteroaryl groups, and optional partial or full deuteration. Named inventors are Peter Wolohan, Tyler Fleetham, Jason Brooks, Rasha Hamze, and Nicholas J. Thompson. CPC classifications include H10K 85/6572, C07D 403/14, C07D 487/04, C09K 11/06.
About this source
USPTO classification C07D covers heterocyclic organic compounds: the chemical core of most small-molecule drugs, including kinase inhibitors, GLP-1 receptor agonists, antibiotics, antivirals, and CNS therapies. Every newly published application in C07D lands in this feed, around 160 a month. Applications publish 18 months after filing, so this feed reveals what medicinal chemistry groups at Pfizer, Novartis, Roche, Shionogi, and others were synthesizing in the prior year and a half. Watch this if you run a medicinal chemistry program, file patent clearance for new drug candidates, scout competitor pipelines before clinical readouts, or track heterocyclic innovation across therapeutic areas.
What changed
Universal Display Corporation has filed patent application US20260114182A1 for a compound of Formula I applicable to organic electroluminescent materials and devices. The claimed compound features a 5-membered or 6-membered aromatic ring structure with nitrogen-containing positions, linked substituents selected from alkyl, cycloalkyl, heteroalkyl, heterocycloalkyl, aryl, and heteroaryl groups, with provisions for partial or full deuteration.
Manufacturers and developers of OLED displays, electronic displays, and related electroluminescent devices should monitor this patent filing for potential licensing implications or competitive landscape considerations regarding novel organic semiconductor compounds with deuterated structures.
