Fluorene derivatives that are connected in one or more of the 1-, 1'-, 4-, or 4'- positions in any combination to a carbon atom of a diaryl substituted triazinyl or pyrimidinyl derivative. The fluorene derivatives are not spiro-bifluorene derivatives. The compounds are suitable for use in electronic devices, in particular organic electroluminescent devices, comprising these compounds. In some embodiments, the compounds are used as matrix materials for phosphorescent or fluorescent emitters as well as a hole-blocking or an electron-transport layer.
