Precise macromolecular engineering has been enabled by various controlled radical polymerization procedures. Copper-based ATRP (atom transfer radical polymerization) catalytic systems with polydentate nitrogen ligands are among most efficient controlled/living radical polymerization systems. By applying new initiating/catalytic systems, Cu level in ATRP was reduced to a few ppm. The activators are regenerated by light, reducing agents, electrical current or mechanical forces. By employing these systems, ATRP of acrylates, methacrylates, styrenes, acrylamides, acrylonitrile and other vinyl monomers was employed for macromolecular engineering of polymers with precisely controlled molecular weights, tuned dispersities, designed shape, composition and functionality. Examples of block, graft, star, hyperbranched, gradient and periodic copolymers, molecular brushes and various hybrid materials and bioconjugates prepared with high precision will be presented. Special emphasis will be on nanostructured multifunctional hybrid materials for application related to environment, energy and catalysis.
