In this research work, We demonstrate the effect of geometrical frustration on molecular configuration, domain morphologies, and phase behavior of the cholesteric BPs in shell geometries as function of shell thickness and boundary condition. The morphologies of BPs confined in shell geometries significantly affected by surface anchoring conditions in which the homeotropic induced anchoring alters BPI domain alignments resulting in 30 nm blue-shift in the reflected color. Moreover, BP confined in shells exhibit the new phase behavior upon reducing the shell thickness. Our experimental observations are accompanied by computational simulations to obtain more insights into the underlying physics of the new orientational principles.
