Abstract: PURPOSE:To obtain a new compound useful as a synthetic intermediate for a condensation-based polymer compound such as polyimide or polyamide containing a liquid crystal group at the side chain, having excellent high-speed responsiveness and shelf stability. CONSTITUTION:A compound of formula I (R to R are alkyl or phenyl; X is single bond, O, COO or OCO; Q is liquid crystal group; (p) and (q) are 2-10) such as a compound of formula II. The compound of formula I, for example, is obtained by reacting a compound of formula III with a compound of formula IV to give a compound of formula V and reducing the dinitro group of the compound of formula V. Both of the compounds of formula III and formula V are new compounds.
