N-(9,9-Dipropyl-9H-fluoren-2-yl)-7-(piperidin-1-yl)-2,1,3-benzothiadiazol-4-amine

In the title compound, C30H34N4S, each of the benzothiadiazole and fluorene fused ring systems is almost planar (r.m.s. deviations = 0.010 and 0.013 , respectively) and they are inclined to each other with a dihedral angle of 61.69 (3)°; the S atom is directed away from the rest of the molecule. Each of the benzothiadiazole ring N atoms forms a significant intramolecular contact, i.e. N—H...N or C—H...N. In the crystal, linear supramolecular chains along the c axis are generated by C—H...N interactions involving the tertiary amine N atom.
