Abstract
(EN)
Disclosed are a naphthothiodibenzofuran unit-based blue light polymer light-emitting material, a preparation method therefor and the use thereof. Sulfonyl in the naphthothiodibenzofuran unit is a strong electron-withdrawing unit that facilitates improving the electron affinity, promoting the injection and transporting of electrons. Moreover, the sulfonyl in the naphthothiodibenzofuran unit is located on a side chain of the polymer, and same has an appropriate conjugate plane, without causing a significant red shift in a spectrum. In the present invention, the naphthothiodibenzofuran unit-based blue light polymer light-emitting material is obtained by means of a Suzuki polymerization reaction, and the light-emitting material is dissolved using a common organic solvent, and then formed into a film by means of spin coating, ink-jet printing or printing to prepare a light-emitting layer of a light-emitting diode, wherein when the light-emitting layer is prepared into a light-emitting device, there is no need for an annealing treatment.

L'invention concerne un matériau polymère électroluminescent de lumière bleue à base d'un motif naphtothiodibenzofuranne, son procédé de préparation et son utilisation. Le sulfonyle du motif naphtothiodibenzofuranne est un motif attracteur d'électrons fort qui facilite l'amélioration de l'affinité électronique, la promotion de l'injection et le transport d'électrons. De plus, le sulfonyle du motif naphtothiodibenzofuranne est situé sur une chaîne latérale du polymère, et présente un plan conjugué approprié sans occasionner de décalage important vers le rouge dans un spectre. Dans la présente invention, le matériau polymère électroluminescent de lumière bleue à base d'un motif naphtothiodibenzofuranne est obtenu au moyen d'une réaction de polymérisation de Suzuki, et le matériau électroluminescent est dissous dans un solvant organique courant, puis transformé en un film au moyen d'un dépôt à la tournette, d'une impression au jet d'encre ou d'une impression pour préparer une couche électroluminescente d'une diode électroluminescente ; quand la couche électroluminescente est installée dans un dispositif électroluminescent, il n'est alors pas nécessaire de procéder à un traitement de recuit.
