The present invention relates to indane derivatives of the formula (I)
and mixtures thereof, wherein X is selected from groups of the formulae -A-NH2 or -A-(NAr2), wherein A is a chemical bond or phenylene which is unsubstituted or substituted by 1, 2, 3 or 4 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 RA, RB, Y, k, l, m, p, q and r 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.
