Abstract

Abstract Synthesis of 2-hydroxy (methoxy)-4, 4′-biphenyldicarboxylic acids was developed. Based on their reactions with o-aminophenols we prepared for the first time 4, 4′-bis [5- alkyl (aryl) benzoxazol-2-yl]-2-hydroxy-(alkoxy) biphenyls, which might be of interest as luminescent dyes. Hydroxy compounds in a salt form possess abnormally high Stokes shift.
