The dispersion of dendrimers in a liquid crystal (LC) is reported as a new approach to LC displays based on light scattering. It is shown that the performance of a fifth-generation palmitoyl-functionalized poly(propylene imine) dendrimer—with 64 “legs”, as shown in the Figure—as an electro-optical switch is superior to that of polymer-filled nematics and polymer-dispersed LC systems (see also cover).
