Kit ou pa yon konpoze òganik emèt limyè ak longèdonn nan emisyon limyè ak efikasite nan emisyon limyè depann sitou sou estrikti a pwodui chimik. Fluoresans anjeneral fèt nan molekil avyon rijid ak sistèm konjige, ki amelyore efè konjigezon elektwonik la ak coplanarite nan molekil yo, ki se benefisye amelyore efikasite nan fluoresans. Gen anpil òganik limyè-fè nwa materyèl yo. Kalite prensipal yo se: spiro bag, poly-p-phenylene vinylene, polythiophene, polythiadiazole ak metal kowòdinasyon konpoze. Nan mitan yo, konpoze aromat espirikik yo gen gwo konjige sistèm ak Bon frigidité ak coplanarite, tanperati tranzisyon anwo nan syèl la ak segondè estabilite tèmik. Aparèy la EL se senp nan pwosesis epi li pa mande pou konplike ekipman, kidonk li posib diminye pri fabrikasyon an pandan peryòd la ak fasil pou prepare aparèy gwo-zòn.

Whether or not an organic compound emits light and the wavelength of light emission and the efficiency of light emission depend mainly on the chemical structure. Fluorescence usually occurs in molecules with rigid planes and conjugated systems , which enhances the electron conjugation effect and the coplanarity of the molecules, which is beneficial to improve the fluorescence efficiency . There are many organic light-dark materials. The main types are: spiro ring, poly-p-phenylene vinylene, polythiophene, polythiadiazole and metal coordination compounds. Among them, spirocyclic aromatic compounds have large conjugated systems and Good rigidity and coplanarity, high glass transition temperature and high thermal stability . The EL device is simple in process and does not require complicated equipment, so it is possible to reduce the manufacturing cost during the period and to easily prepare large-area devices.
