The present invention provides a hole-transporting or hole-injecting material for an optoelectronic device, comprising a compound of the formula (I) and/or a compound of the formula (II), (I) (II) wherein: Ar1 and Ar2 independently represent an optionally substituted arylene group, an optionally substituted heteroarylene group or an optionally substituted fluorenylene group; R1 and R2 independently represent hydrogen or a group -NAr6Ar7, wherein Ar6 and Ar7 are independently an optionally substituted aryl group, an optionally substituted heteroaryl group, or an optionally substituted fluorenylene group, and wherein a direct covalent bond may be present between Ar6 and Ar7 such that a fused heterocyclic ring system is formed which contains Ar6, Ar7 and the nitrogen atom to which they are attached; L1 and L3 independently represent a bond, an optionally substituted arylene group, an optionally substituted fluorenylene group, or an optionally substituted heteroarylene group; and L2 represents a bond, an optionally substituted arylene group, an optionally substituted heteroarylene group, an optionally substituted fluorenylene group, or a group - Ar3-N(Ar4)-Ar5-, wherein Ar3 and Ar5 represent optionally substituted arylene groups, and Ar4 represents an optionally substituted aryl group.
本发明提供了一种用于光电子器件的传输孔或注入孔的材料,包括符合式(I)的化合物和/或符合式(II)的化合物,其中:Ar1和Ar2分别代表可选择取代的芳基、可选择取代的杂芳基或可选择取代的芬啶基;R1和R2分别代表氢或基团-NAr6Ar7,其中Ar6和Ar7分别代表可选择取代的芳基、可选择取代的杂芳基或可选择取代的芬啶基,并且Ar6和Ar7之间可能存在直接共价键,形成包含Ar6、Ar7和它们附着的氮原子的融合杂环系统;L1和L3分别代表键、可选择取代的芳基、可选择取代的芬啶基或可选择取代的杂芳基;L2代表键、可选择取代的芳基、可选择取代的杂芳基、可选择取代的芬啶基或基团-Ar3-N(Ar4)-Ar5-,其中Ar3和Ar5代表可选择取代的芳基,Ar4代表可选择取代的芳基。
