Chemists report they've made the first nonspherical dendrimers—densely branched polymers that are usually in the shape of a ball. The new ones are shaped like rods, however, and that asymmetry may allow them to serve as liquid crystals (LCs): the hybrid molecules that flicker between solid and liquid states to form watch and computer displays. It's taken powerful electric fields to make polymers flicker like LCs in the past; the dendrimers flicker much more readily.
