Rheological behavior across thermal phase transitions of liquid crystalline (LC) structures has been investigated using dendron-modified LC gold nanoparticles (NPs) prepared by surface modification of spherical gold NPs with LC dendrons. Such dendron-modified gold NPs self-organize to form a columnar LC structure that transforms to a simple cubic LC structure with increasing temperature. Endo- and exothermic peaks associated with this phase transition are barely observable. However, using dynamic viscoelastic measurements, the transition was observed as a drastic increase in fluidity of the dendron modified gold NPs.
