The present invention relates to indane derivatives of the formula (I) and mixtures thereof, wherein X is selected from groups of the formula -A-(NAr2), wherein A is a chemical bond or phenylene which is unsubstituted or substitutedby 1, 2 or 3 substituents selected from C1-C6-alkyl and C1-C6-alkoxy; Ar is unsubstituted or substituted aryl, wherein two groups Ar bound to the same nitrogen atom may together with the nitrogen atom also form a fused ring system having 3 or more than 3 unsubstituted or substituted rings; and the variables Y, n, m, k and l are as defined in the claims and the description. The invention further relates to methods for preparing such compounds and their use in organic electronics, in particular as hole transport material or electron blocking material.
本发明涉及公式(I)及其混合物的
茚烷衍
生物,其中X选自公式-A-(NAr2)的基团,其中A是未取代或取代为1、2或3个选自C1-C6烷基和C1-C6烷氧基的取代基的
化学键或苯基;Ar是未取代或取代的芳基,其中结合到同一氮原子的两个Ar基团可能与氮原子一起形成具有3个或3个以上未取代或取代环的融合环系统;变量Y、n、m、k和l如权利要求和描述中所定义。该发明还涉及制备这类化合物的方法以及它们在有机电子学中的用途,特别是作为空穴传输材料或电子阻挡材料。
