Abstract

The present invention relates to substituted boron or aluminum spiro compounds and their use in the electronic industry. The compounds of the invention are used as electron transport material, hole blocking material and/or as host material in organic electroluminescence and/or phosphorescence devices, as electron transport material in photocopiers, as electron acceptor or electron transport material in solar cells, as charge transport material in organic ICs (circuits) and in organic solid-state lasers or organic photodetectors.
