The title compound, C32H21N4·C2H5OH, crystallized as an ethanol monosolvate. In the molecule of this phenanthroline derivative, the pyridine rings are almost coplanar, making a dihedral angle of 1.54 (13)°. The triphenylamine group, introduced as an electron donor, shows a propeller-type structure, and the dihedral angles between the benzene rings are 68.71 11), 63.92 (16) and 70.81 (15)°. In the crystal, the phenanthroline molecules are linked via the solvent molecule by N-HO, O-HN and C-HO hydrogen bonds, leading to the formation of zigzag chains propagating along . These chains are linked via C-HN hydrogen bonds, forming undulating two-dimensional networks extending in the a- and b-axis directions.
