摘要： A cholesteric display including a cholesteric liquid crystal, and a dipolar dopant having limited miscibility in the cholesteric liquid crystal is provided. In accordance with another aspect, a process is provided for forming a cholesteric liquid crystal composition by dissolving a dipolar dopant having limited solubility into a cholesteric liquid crystal. The liquid crystal composition can be utilized to produce a cholesteric display. The liquid crystal domains in the liquid crystal composition rotate away from a planar state in the presence of an applied electric field and the degree of rotation is a function of the applied electric field strength. The reflected color is then a function of the applied electric field.

摘要： A method for determining whether an item has been exposed to an environmental condition during a monitoring period. The method includes placing a sensor at least in proximity to the item at the beginning of the monitoring period so that the sensor will be exposed to a level of an environmental condition that can be correlated to an exposure level of the item to the environmental condition; reading the sensor; and determining from reading the sensor whether the item has been exposed to the environmental condition. The sensor includes a detecting material comprising a photochromic or photothermochromic material, the detecting material selected so that upon exposure to the environmental condition the detecting material exhibits a detectable color change.
