This picture was obtained for a four ring achiral bent core compound with 2-methyl-3-amino-benzoic acid as the central core and a methoxy substituent at one end of the four-ring bent-core liquid crystal consisting of an azo benzene group in the longer side arm and a salicyldimine moiety bearing a hydroxyl chain at the other end. The image is taken in a normal glass plate covered with a glass slip at 145ºC under a Nikon Polarising microscope (Nikon optiphot-2-pol) attached with Instec STC 200 hot stage and Nikon Digital sight DS-Fi1 digital camera. The image height is about 100 microns.

The archetypal texture of a nematic picture with 2 and 4 brush defects is stunning simple and beautiful.
