    Controlling a Polymer Adhesive Using Light and a Molecular Switch

    A thermally remendable polymer was synthesized by the Diels–Alder reaction between dithienylfuran and maleimide monomers to generate a photoresponsive diarylethene. UV light (312 nm) and visible light (>435 nm) “gate” the reversibility of the Diels–Alder reaction and turn the self-healing properties of the polymer “off” and “on”, respectively. After exposure to UV light, the strength of the polymer as an adhesive is enhanced. Visible light weakens the adhesive
