Cover Picture: Aluminum Complexes Stabilized by Piperazidine-Bridged Bis(phenolate) Ligands: Syntheses, Structures, and Application in the Ring-Opening Polymerization of ε-Caprolactone (Chin. J. Chem. 3/2012)
The cover picture shows a series of aluminum alkoxide and alkyl complexes modified by piperazidine-bridged bis(phenolate) ligands, which were used with great success for the ring-opening polymerization (ROP) of ¦Å-caprolactone (ε-CL), a renewable resource due to their biodegradability/biocompatibility. All of these complexes were fully characterized including X-ray structural determination. More details are discussed in the article by Yao et al. on page 609–615.
