- Method for synthesizing indane structure-containing compound
-
The invention provides a method for synthesizing an indane structure-containing compound, which comprises the following steps: 1) in the presence of a solid acid catalyst, carrying out a nitration reaction on an indane compound of a compound as shown in a general formula (I) to obtain compounds as shown in a general formula (II) and a general formula (III); and 2) in the presence of a reducing agent, performing a reduction reaction on the compounds represented by the general formula (II) and the general formula (III) to obtain compounds represented by the general formula (IV) and the general formula (V); wherein in the general formulas (I), (II), (III), (IV) and (V), R1, R2, R3 and R4 are independently hydrogen, C1-4 alkyl, C1-4 alkoxy, halogen, hydroxyl or carboxyl.

- INDANE DERIVATIVES AND THEIR USE IN ORGANIC ELECTRONICS
-
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.
