A delayed fluorescence material in accordance with the present disclosure may comprise a compound having a molecular structure including an electron donor unit and an electron acceptor unit coupled to the electron donor unit, wherein the electron donor unit includes an acridine furan derivative formed by acridine being bonded to dibenzofuran. The delayed fluorescence material may allow high structural and thermal stabilities and improved quantum efficiency.
The present invention provides a polymerizable compound having high storage stability without causing crystal precipitation when added to a polymerizable composition. The present invention also provides a polymerizable composition containing the compound. When the filmy polymer produced through polymerization of the polymerizable composition is irradiated with UV light, it hardly discolors or peels from substrate. Further, the present invention provides a polymer produced through polymerization of the polymerizable composition and an optically anisotropic body using the polymer.
