Ring-opening metathesis polymerization (ROMP) of cyclic olefins has been widely used in the synthesis of advanced polymeric materials. This mini review introduces the basics of olefin metathesis reactions, especially ROMP, and summarizes reported examples of cis-/trans- (Z-/E-) specific ROMP in which ruthenium-carbene, molybdenum-alkylidene, vanadium-alkylidene, and niobium-alkylidene catalysts were used. cis-/trans-Selective bottlebrush polymers prepared from (arylimido)vanadium(V)-alkylidene catalysts displayed different thermal and emission properties because of their different morphologies and interpolymer and/or intrapolymer interactions.
