摘要

A novel and efficient strategy in obtaining series of mono- and bi-armed azobenzene-containing poly(epsilon-caprolactone) s is described, starting from a commercially available azobenzene dye via azide/alkyne"click"-reactions. The attachment of alkyne-telechelic poly(epsilon-caprolactone) s (1 kDa and 3 kDa), followed by chromatographic separation, allowed the attachment of either one or two PCl-chains to either side of the azobenzene-dye. The resulting mono-and bi-armed photo-switchable polymers are fully characterized by 2D-NMR techniques and show a high thermal stability. Additionally liquid chromatography at critical conditions (LCCC) coupled to ESI-TOF allowed us to prove the presence of either one or two polymer chains affixed onto the central azobenzene dye.
