Abstract:
1. A device comprising: a liquid crystal composition including a liquid crystal and a liquid crystal domain stabilizing compound, wherein the liquid crystal composition switches between a strongly scattering state of a first plurality of smaller liquid crystal domains that strongly scatters a predetermined light and a weakly scattering state of a second plurality of larger liquid crystal domains that weakly scatters the predetermined light; and a liquid crystal containment structure defining a space for the liquid crystal composition, wherein the liquid crystal domain stabilizing compound is a compound having formula (2) wherein A2 is an electron acceptor moiety; C2 is a conjugated bridging moiety; D2 is an electron donor moiety; S2 is a liquid crystal compatibilizing moiety; a′ is an integer; Z2 is a polymerizable moiety; and e′ is the degree of polymerization.
