Effective Ligand Design: Zinc Complexes with Guanidine Hydroquinoline Ligands for Fast Lactide Polymerization and Chemical Recycling.

Invited for this month's cover is the group of Sonja Herres-Pawlis at RWTH Aachen University. The image shows how the zinc guanidine complexes help a circular economy of bioplastics by mediating the ring-opening polymerization of lactide and the depolymerization of polylactide (PLA).
