PYRAZOLE COMPOUNDS FOR ORGANIC LIGHT EMITTING DIODES AND OTHER APPLICATIONS
The present disclosure generally relates to emitting organic molecules, including but not limited to, pyrazoles such as 2-phenyl-2H-pyrazol-3-yl acetate, etc. In some cases, the molecules are able to emit in blue or green wavelengths. In some aspects, such molecules may be used in organic light emitting diodes. In certain embodiments, the molecules may comprise one or more bridge moieties and one or more chromophores. In some embodiments, these molecules can be used as electroluminescent media in devices requiring light emission as a function of applied voltage. Other embodiments of the disclosure are generally directed to systems and devices using such molecules, methods of using such molecules, e.g., to control the emission of light, kits involving such molecules, or the like.
