Compound with ligand la and specific structural features
A recently filed patent (Publication Number: US20230320188A1) describes a compound with potential applications in organic light-emitting devices (OLEDs). The compound consists of a ligand (LA) coordinated to a metal (M) through specific bonding arrangements. The ligand can form tridentate, tetradentate, pentadentate, or hexadentate ligands by joining with other ligands. The compound can have various substituents, including hydrogen, deuterium, halogens, alkyl groups, cycloalkyl groups, heteroalkyl groups, aryl groups, and many others. The compound can also have different ring structures, including monocyclic or polycyclic rings comprising 5-membered and/or 6-membered carbocyclic or heterocyclic rings.
The patent also describes the use of the compound in organic light-emitting devices (OLEDs). OLEDs are electronic devices that emit light when an electric current is applied. The compound can be incorporated into the organic layer of the OLED, which is situated between the anode and cathode. The organic layer may also contain a host material, which can be selected from a range of chemical moieties such as triphenylene, carbazole, indolocarbazole, and others.
The compound described in the patent has potential applications in the development of OLEDs, which are used in various consumer products such as smartphones, televisions, and lighting fixtures. The compound's unique ligand structure and coordination with a metal provide opportunities for improved performance and efficiency in OLED devices. However, further research and development are needed to fully explore the compound's potential and optimize its properties for commercial use.
