(4z,5e,9e,10z)-n4,n5,n9,n10-tetrakis(2,6-diisopropylphenyl)pyrene-4,5,9,10-tetraimine

The title molecule, C64H74N4, consists of a pyrene backbone with imine moieties located on the 4-, 5-, 9-, and 10-positions of the ring system. The aryl groups on these imines are sterically bulky 2,6-diisopropylphenyl units. As a consequence, the backbone itself is twisted, with an angle of 15.29 (6)° between the mean planes (r.m.s. deviations = 0.006 and 0.009 Å) of the phenyl units. The N=C—C=N units are significantly twisted and feature torsion angles of −48.8 (2) and −46.3 (3)°. The non-planarity of the backbone and short C—N distances [ranging from 1.281 (2) to 1.285 (2) Å] indicate the lack of conjugation in the molecule and double-bond nature of the imines. Weak intramolecular and intermolecular C—H...π interactions are observed.
