Stable Activated Furan and Donor–Acceptor Stenhouse Adduct Polymer Conjugates as Chemical and Thermal Sensors

The development and application of novel activated furan copolymers is reported. The platform provides a colorimetric method for sensing amines in aqueous media through the generation of a highly colored donor acceptor Stenhouse adduct (DASA). Furthermore, the resulting DASA polymer conjugates, which are obtained after amine sensing, are characterized to determine fundamental structure property relationships for this emerging class of negative photochromic species.
