Liquid crystalline derivatives for electronic devices

摘要

The present invention is related to a device comprising a liquid crystalline poly-aza-trinaphthylene derivatives of the structure I: <CHEM> wherein A is C-R or N (nitrogen), and B is R1 R is hydrogen (H) or deuterium (D) halogen (F, Cl, Br or I) nitro (NO2) nitryl (CN) R1 is ether (O-R2) ester (O-CO- R2 or CO-O- R2) alkyl (R2) alkyne (C C- R2) phenyl (mono, di or tri substituted by above-mentioned R2 groups) with R2 being an alkyl, branched or not, an oligoether, or a combination of both, of 5 to 20 carbon atoms. <IMAGE>
