N2-(7-Bromo-9-butyl-9H-carbazol-2-yl)-9,9-diethyl-N2,N7,N7-triphenyl-9H-fluorene-2,7-diamine

Abstract

In the title molecule, C51H46BrN3, the central fluorene residue is planar (r.m.s. deviation = 0.0203 Å), as is the carbazole system (r.m.s. deviation = 0.0154 Å), and these groups are almost orthogonal [dihedral angle = 79.72 (3)°]. The three-dimensional architecture is consolidated by C—H...π interactions. The butyl substituent is disordered with two sites resolved for the terminal propyl atoms; the major component had a site-occupancy factor of 0.686 (3).
