A series of aluminum complexes bearing phenolate (O–Al and O2–Al), biphenolate (OO–Al type), aminophenolate (ON–Al), aminobiphenolate (ONO–Al), bis(phenolato)bis(amine) (NNOO–Al), and Salan (ONNO–Al) type ligands were synthesized.
New Zr(IV) and Hf(IV) complexes were synthesized and applied as molecular precursors for chemical vapor deposition (CVD) of zirconium-, hafnium-, and mixed hafnium–zirconium–oxide (HZO) coatings.
RAFT step-growth polymerization is an emerging method that synergistically combines the benefits of RAFT polymerization (functional group and user-friendly nature) and step-growth polymerization (versatility of the polymer backbone).
Cationic copolymerization of vinyl ethers and spiroorthoesters successfully proceeded via very frequent crossover reactions, resulting in pseudo-alternating copolymers with acid degradability.
Demonstrated is the successful A2 + B2 RAFT step-growth polymerization of bis-acrylamides. The synthesized poly(acrylamides) can be degraded by simply adding excess ethanolamine or PBu3.
