چکیده
In the crystal structure of the title compound, C(25)H(20)N(4), the triazinyl ring is nearly coplanar with the planar (r.m.s. deviation = 0.028 Å) phenyl-ethenyl unit, the twist being only 5.8 (2)°; however, the planar carbazolyl unit (r.m.s. deviation = 0.008 Å) is twisted by 47.8 (1)° with respect to the phenyl-ethenyl unit. The nonplanar nature of the mol-ecule explains the phenomenon of light emission at short wavelengths in the solid state but at long wavelengths in solution.

In the title mol-ecule, C(26)H(25)Br(3)N(2), a dihedral angle of 6.15 (10)° is present between the carbazole and benzene ring systems with an E conformation about the C=C bond [1.335 (4) Å]. The butyl group is almost perpendicular to the carbazole plane [C-N-C-C torsion angle = -98.7 (3)°]. In the crystal, supra-molecular double chains along [-7,18,-16] are formed via C-H⋯Br and π-π inter-actio...

The title compound, C(54)H(48)N(2)O(2), lies about an inversion centre. The carbazole ring system makes dihedral angles of 58.43 (7) and 88.96 (7)°, respectively, with the adjacent and central benzene rings. The dihedral angle between the two benzene rings is 52.01 (8)°. In the crystal, mol-ecules are linked by pairs of C-H⋯O inter-actions, forming a tape along the a axis. The methyl group is d...
