Heller, Marcel; Schubert, Ulrich S.
- Abstract:
- Chiral polyesters, end-capped with terpyridine,
were prepared via the coordinative ring-opening
polymerization of l-lactide. Stable supramolecular dimer
structures resulted after complexation with iron(II) ions.
The formation of both the macroligands and the polymer
complexes was proven for the first time clearly by means
of GPC coupled to an in-line photodiode array UV/Vis
spectrophotometer, NMR spectroscopy and MALDI-TOF
mass spectrometry. A sensitivity of the iron(II)-centered
poly(l-lactide)s towards UV irradiation and thermal or pH
changes could be observed.
