In the title compound, C24H19NOS, the quinoline residue (r.m.s. deviation = 0.018 Å) is essentially orthogonal to both the phenyl [dihedral angle = 88.95 (8)°] and 2-thienyl [81.98 (9)°] rings. The carbonyl O atom lies to one side of the quinoline plane, the carbonyl C atom is almost coplanar and the remaining atoms of the chalcone residue lies to the other side, so that overall the mol-ecule has an L-shape. The conformation about the ethyl-ene bond [1.340 (2) Å] is E. In the crystal, a supra-molecular chain with the shape of a square rod aligned along the b-axis direction is sustained by C-H⋯π inter-actions, the π-systems being the heterocyclic rings.
在标题化合物C₂₄H₁₉NOS中，喹啉残基（均方根偏差 = 0.018 Å）与苯基 [二面角 = 88.95 (8)°] 和2-噻吩基 [81.98 (9)°] 环基本正交。羰基O原子位于喹啉平面的一侧，羰基C原子几乎共面，查耳酮残基的其余原子位于另一侧，因此整个分子呈L形。乙烯键 [1.340 (2) Å] 的构象为E型。在晶体中，由C—H⋯π相互作用维持着沿b轴方向排列成方棒状的超分子链，π体系为杂环。
