At least two electron acceptors for use in organic electronic devices and a phenyl derivative substituted with at least two electron donors

摘要

The present invention relates to phenyl-derivative compounds of formula (I) substituted with at least two electron acceptors and at least two electron donors.^A_a R _b R ^SD R _c C ₆ (I) In expression a is 2, 3 or 4; b is 2, 3 or 4; c is 0, 1 or 2; a + b + c = 6; R ^A is independently at each occurrence a group having a -M- effect; R ^D is a group independently of each occurrence having a + -M- effect; R ^{S is} as defined in claim 1. The compounds are suitable for use in organic electronic devices, especially organic electroluminescent devices.
