چکیده
The title compound, C(26)H(20)N(2)O, belongs to a new family of organic two-photon absorption materials with triphenyl-amine and pyridine units. In the mol-ecule, the three benzene rings are arranged in a propeller-like fashion; the dihedral angles between the rings are 80.01 (14), 75.68 (13) and 56.93 (14)°. The pyridine ring is oriented at dihedral angles of 56.24 (14), 48.92 (15) and 22.02 (13)° with respect to the three benzene rings. Weak inter-molecular C-H⋯O hydrogen bonding is present in the crystal structure.

The mean planes of the benzene and pyridine rings in the title compound, C(15)H(12)BrNO(2), are nearly coplanar, subtending an angle of 2.8 (8)°. The prop-2-en-1-one group is also in the plane of these rings with an N-C-C-O torsion angle of 179.6 (3)°. A weak C-H⋯Br inter-molecular inter-action contributes to the crystal packing, creating a chain-like structure along the a axis.
