The invention discloses a compound for encapsulating organic light-emitting devices, a preparation method and application thereof, and belongs to the technical field of thin-film encapsulation of organic light-emitting devices. The compound L has the following structure. At the same time, the present invention also provides a composition prepared from compound L, acryl compound, and one or more of photopolymerization initiators and radical polymerization initiators, and the composition is applied in the packaging of organic light-emitting devices When the encapsulation film exhibits low oxygen and moisture transmittance, the life of the organic light-emitting device can be prolonged, and the etching resistance of the organic layer to plasma can be enhanced to obtain an organic/inorganic hybrid encapsulation with higher flatness. Film encapsulation compositions, encapsulation films, and display devices utilizing these. |
