AbstractChiral poly(L-lactide)s end-capped with a novel terpyridine ligand are synthesized by a controlled coordinative polymerization procedure. The resulting well-characterized macroligands can be complexed under phase-transfer conditions with iron(II) ions to form well-defined supramolecular poly(L-lactide) complexes. The outstanding stability of such coordinative polymers enables the full characterization by gel permeation chromatography (GPC) and MALDI-TOF mass spectrometry. In addition, in-line diode array UV-Vis spectroscopy coupled to GPC was carried out to verify the formation of the poly(ester) complexes.

Macroheterocyclic Compound

A monoiododi(tert-butyl)substituted macroheterocyclic compound of ABAB[Formula: see text]AB[Formula: see text]-type 4 was obtained, as a mixture of regioisomers, by statistical condensation of 4-iodophthalonitrile, 4-tert-butylphthalonitrile and 2,5-diamino-1,3,4-thiadiazole in a molar ratio 1:2:3 respectively. The structure of the functionalized hemihexaphyrazine was confirmed by MALDI-TOF mass spectrometry, IR and UV-vis spectroscopy.
