Abstract :
The title molecule, C20H20B2F4N4, assumes a planar conformation with all atoms apart from the F atoms lying on the symmetry plane. Each boron atom is four-coordinated by two fluorine atoms, a pyrrole N atom and an imine N atom. Both imine CH=N groups adopt a trans conformation. In the crystal, the molecules self-assemble into a pillar structure through C—H⋯F hydrogen bonds and π–π interactions. The UV–vis spectrum and fluorescence spectra of the title compound are also reported.
