Liquid crystalline derivatives for multilayer electronic devices

摘要

The present invention is related to a mesogen material , soluble in high polarity solvents, based on a poly-aza-trinaphthylene of the structure I: <CHEM> wherein A is C-R4 or N (nitrogen), and n is the number of ethyleneoxy units in each chain. R2 is ether (O-R3) ester (O-CO- R3 or CO-O- R3) ketone (CO-R3) alkyl (R3) R4 is hydrogen (H) or deuterium (D) halogen (F, Cl, Br or I) nitro (NO2) nitryl (CN) with R1 and R3 being an alkyl group, branched or not, of 1 to 10 carbon atoms. The number of ethyleneoxy units n is fixed between 1 and 6. <IMAGE>
