The title chiral photochromic Schiff base compound, C21H19N3O2, was synthesized from (R)-(−)-2-phenylglycinol and salicylaldehyde of azobenzene derivative. The molecule exhibits the keto–amine tautomeric form and displays characteristic features of azobenzene derivatives. The diazenyl group adopts a trans (E) conformation, with N=N bond length of 1.260 (2) Å. The hydroxy group is involved in an intermolecular O—H...O hydrogen bond.
