In article number 1700119 , Jang‐Kun Song and co‐workers demonstrate the controlled in situ molecular transfer between the heterogeneous liquid crystal (LC) microdroplets in an LC emulsion. Chiral dopants can be transferred between nematic and cholesteric LC droplets, which are the receiver and supplier of chiral molecules, respectively, and a continuous phase with tunable solubility acts as the switchable transfer channel. The molecular transfer is visually monitored by the topological transition and the change in the photonic crystalline reflection colors of the LC droplets.
