    • The present invention relates to electronic devices, especially electroluminescent devices, comprising azapyrenes of formula (I), or formula (III), wherein Y1, Y2, Y3, Y4, X1, X2 and X3 are independently each other N, or CR4, with the proviso that at least one of the groups X1, X2 and X3 is a group CR4, R1 is hydrogen, F, —SiR100R101R102, or an organic substituent, R4 is hydrogen, F, —SiR100R101R102, or an organic substituent, or any of the substituents R1, R1′ and R4, which are adjacent to each other, together form an aromatic, or heteroaromatic ring, or ring system, which can optionally be substituted, m is an integer of 1 to 6, and R100, R101 and R102 are independently of each other a C1-C8alkyl group, a C6-C24aryl group, or a C7-C12aralkyl group, which may optionally be substituted, and Q is a linking group; with the proviso that in the compound of formula (III) at least one of the substituents R1, or R4 is a group Q; especially as host for phosphorescent emitters, electron transporting materials, or emitter materials. The hosts may function with phosphorescent materials to provide improved efficiency, stability, manufacturability, or spectral characteristics of electroluminescent devices.
    • 本发明涉及包含式(I)或式(III)的吡喃酮的电子器件,特别是电致发光器件,其中Y1,Y2,Y3,Y4,X1,X2和X3彼此独立地为N或CR4,与 条件是基团X1,X2和X3中的至少一个是基团CR4,R1是氢,F,-SiR100R101R102或有机取代基,R4是氢,F,-SiR100R101R102或有机取代基,或任何 彼此相邻的取代基R 1,R 1'和R 4一起形成可任选被取代的芳族或杂芳族环或环系,m是1至6的整数,且R 100,R 101和R 102 彼此独立地为C1-C8烷基,C6-C24芳基或可任意取代的C7-C12芳烷基,Q为连接基团; 条件是在式(III)的化合物中,至少一个取代基R 1或R 4为基团Q; 特别是作为磷光发射体,电子传输材料或发射体材料的主体。 主机可以与磷光材料一起工作,以提供电致发光器件的改进的效率,稳定性,可制造性或光谱特性。
