(E)-3-[4-(Diphenyl­amino)­phen­yl]-1-(pyridin-2-yl)prop-2-en-1-one

Abstract

The title compound, C26H20N2O, belongs to a new family of organic two-photon absorption materials with triphenyl­amine and pyridine units. In the mol­ecule, 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 inter­molecular C—H⋯O hydrogen bonding is present in the crystal structure
