Recent results for synthesis of end-functionalized polymers (EFP) by using olefin metathesis polymerization have been introduced including basic characteristics in ring-opening metathesis polymerization (ROMP) of cyclic olefins and acyclic diene metathesis (ADMET) polymerization for synthesis of conjugated polymers. Several approaches were demonstrated for synthesis of EFP by living ROMP using molybdenum (exclusive coupling with aldehyde) and ruthenium catalysts (sacrificial ROMP, chain transfer). Cis specific (Z selective) ROMPs were achieved by molybdenum, ruthenium, and vanadium catalysts by the ligand modification. The catalytic synthesis of EFP with high cis selectivity has been achieved by combined ROMP with chain transfer by V(CHSiMe3)(N-2,6-Cl2C6H3)[OC(CF3)3](PMe3)2. The ADMET polymerization using molybdenum and ruthenium catalysts afforded defect-free, high molecular weight poly(arylene vinylene)s containing all trans olefinic double bonds. The methods for precise synthesis of EFPs, exhibiting unique optical properties combined with the end groups, were developed. The catalytic one-pot syntheses for EFPs have also been developed.

烯烃复分解聚合:用于高级材料合成的精确聚合的一些最新进展(通过ROMP,ADMET进行)

已经介绍了使用烯烃复分解聚合合成末端官能化聚合物(EFP)的最新结果,包括环烯烃的开环复分解聚合(ROMP)和用于合成共轭聚合物的非环状二烯复分解(ADMET)聚合的基本特征。通过使用钼(与醛的排他性偶联)和钌催化剂(牺牲ROMP,链转移)的活性ROMP,证明了几种合成EFP的方法。通过钼,钌和钒催化剂通过配体修饰获得顺式特异性(Z选择性)ROMP。EFP的具有高催化合成顺式选择性已被合并的ROMP与用V链转移实现(CHSiMe 3)(N-2,6-Cl 2 C 6 H 3)[OC(CF 33 ](PMe 32。使用钼和钌催化剂进行ADMET聚合可得到无缺陷的,包含所有反式烯烃双键的高分子量聚(亚芳基亚乙烯基)。已开发出精确合成EFP的方法,该方法具有独特的光学特性以及端基。也已经开发了用于EFP的催化一锅合成法。
