Abstract
Recent progress in structure-controlled synthesis of π-conjugated polymers is described. A particular interest is focused on transition-metal-catalyzed polymerization that enables precise control of molecular weights and stereoregularity of polymers. The topics include: (a) chain-growth polycondensation to afford polythiophene, polyphenylene, and polyfluorene; (b) living ring-opening metathesis polymerization to give poly (phenylenevinylene); (c) polyaddition reactions based on stereoselective hydrosilylation and dimerization of alkynes; (d) stereocontrolled synthesis of poly (arylenevinylene)s (PAVs). The unique photochemical properties of PAVs are described.
