摘要：

Facile, exclusive end functionalization of poly(9,9-di-n-octylfluorene-2,7-vinylene) (PFV), prepared by acyclic diene metathesis polymerization using Ru(CHPh)(Cl)(2)(IMesH(2))(PCY3) [IMesH(2) = 1,3-bis(2,4,6-trimethylphenyl)-2-imidazolidinylidene], has been achieved by treating the vinyl groups in PFV chain ends with Mo(CHCMe2Ph)(N-2,6-Me2C6H3)[OCMe(CF3)(2)](2) followed by Wittig-type cleavage with 4-Me3SiOC6H4CHO; precise synthesis of ABA type amphiphilic triblock copolymers has been accomplished by grafting PEG into both the PFV chain ends.
