In the molecule of the title compound, C24H20N4O2S, the dihedral angle between the triazole and thiophene rings is 66.80 (4)° and the dihedral angle between the two benzene rings is 63.37 (4)°. An intramolecular C—H⋯O interaction results in the formation of a six-membered ring. A π⋯π contact between the benzene rings, [centroid–centroid distance = 3.918 (2) Å] may stabilize the structure. Weak C—H⋯π interactions are also present. The S, C and H atoms of the thiophene ring are disordered over two positions and were refined with occupancies of 0.654 (3) and 0.346 (3).
