Photoregulation of Retro-Diels–Alder Reaction at the Center of Polymer Chains

Photoregulation of Retro-Diels–Alder Reaction at the Center of Polymer Chains

Photoregulation of polymer chain scission based on a Diels–Alder (DA) adduct containing diarylethene (DAE) was investigated. Poly(ε-caprolactone) with a DA adduct conjugated with DAE skeleton (DAE/DA) at the center of the chain was synthesized by ring-opening living cationic polymerization of ε-capr...

Zusammenfassung:Photoregulation of polymer chain scission based on a Diels–Alder (DA) adduct containing diarylethene (DAE) was investigated. Poly(ε-caprolactone) with a DA adduct conjugated with DAE skeleton (DAE/DA) at the center of the chain was synthesized by ring-opening living cationic polymerization of ε-caprolactone, initiating from diol-type DAE/DA, and its chain scission via thermally induced retro-DA reaction was successfully controlled by photoisomerization of DAE.
