The title compound, C31H22N2, crystallizes with two symmetry-independent molecules in the asymmetric unit. The molecules have slightly different conformations, the dihedral angles between the central phenyl ring and the carbazolyl groups being 56.29 (4) and 59.57 (4)° in one molecule and 48.71 (4) and 65.47 (4)° in the other. In the crystal, molecules are linked by weak C-H and - [centroid-centroid distances = 3.7698 (10), 3.8292 (9), 3.9429 (10) and 3.9431 (10) Å].
