    • In related experiments mixing Au1 or Au2 (at 5 wt%) with the non-liquid crystalline host BC11 a similar shift and broadening of the SPR band was not observed. In this case the bent-core LC decorated gold NPs are not well dispersible in the room temperature crystal modification of BC11, i.e. the gold NPs aggregate and separate from the crystallizing BC11 upon slow evaporation of the solvent. After complete removal of the solvent, heating to the isotropic liquid phase (∼100 °C) and subsequent cooling to room temperature results in the crystallization of BC11 (at 93 °C) and again to the aggregation and separation of the gold NPs. So far, this "immiscibility effect" appears to be general for the functionalized gold NPs and LC materials tested in our laboratory

    • In a recent paper, Kaur et al. reported on a ferroelectric LC (FLC) doped with gold nanoparticles, where the presence of the gold colloids generated higher tilt angles, memory effects, and lower threshold voltages. The authors associated these effects to interactions between the electron wave oscillations in the gold cluster with the incident light traversing through the FLC molecules.
