Triptycene derivatives, and their use for opto-electronic applications, in particular as electroluminescent materialsTriptycene devices of the formula (I)where the symbols in the formula have the following meanings:K1, K2 and K3 are identical or different and are mono- or polycyclic systems, which may, if desired, contain heteroatoms, preferably N, S and/or O, and;X and Y are identical or different and are CR1, N, P, As or SiR2;R1 are identical or different and are H, halogen, pseudohalogen or a hydrocarbon radical having 1 to 30 carbon atoms, which may also, if desired, contain heteroatoms, preferably -O-, -N- and/or -S-;R2 are identical or different and are a hydrocarbon radical having 1 to 30 carbon atoms, which may also, if desired, contain heteroatoms, preferably -O-, -N- and/or -S-,are suitable for use in electroluminescent devices.
