Bismuth(III) Complexes Based on Bis(triazol) Ligands: Effect of Fluorine Substitution on the Structure and Catalysis for the Polymerization of Glycolide

Abstract

(Fbtx) were synthesized and characterized. Single-crystal X-ray diffraction revealed that 1 is a coordination polymer consisting of an anionic one-dimensional chain, whereas 2 shows a discrete ionic-

Synthesis, Microstructure, and Properties of High-Molar-Mass Polyglycolide Copolymers with Isolated Methyl Defects

“…31 Chen and co-workers studied the synthesis and catalytic activities of bis(triazol) derivatives of Bi 3+ complexes with fluorinated and nonfluorinated ligands in the bulk ROP of G and attained high-molar-mass (52 kg• mol −1 ) PGA homopolymers. 32 The melt ring-opening transesterification polymerization of PLAs has been studied using bismuth (III) subsalicylate (BiSS), an effective, relatively lowcost, and commercially available catalyst. 33 Low-molar-mass PGA samples display lower crystallinity, relatively poor thermal and mechanical behavior, and higher water permeability.…”
