    摘要: A method for producing a photochromic polyester, the method including: a) providing a reaction solution having at least one ester monomer, a photochromic compound having or functionalized to have at least one hydroxyl group, and a metal-free catalyst; b) reacting the at least one ester monomer and the photochromic compound using the metal-free catalyst to produce a polymeric product, where the polymeric product has a photochromic polyester; and c) separating the polymeric product from the reaction solution. A photochromic polyester includes a photochromic compound covalently linked to a polyester and the polyester is obtained by polymerizing a lactone.

    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.
