The title chalcone derivative, C24H18O2, which consists of the substituted 4-methoxyphenyl and anthracene rings bridged by the prop-2-en-1-one unit, exists in a cis configuration. The molecule is twisted, the interplanar angle between the benzene and anthracene rings being 69.50 (10)°. The methoxy group is coplanar with the attached benzene ring [C—O—C—C angle = 2.9 (3)°]. In the crystal structure, molecules are linked into chains along the a axis by a weak C—H...O(enone) interaction. The chains are stacked along the c axis. A C—H...π interaction involving the benzene ring is observed.
