Nothing ROMP with that: Unsymmetrical double‐stranded ladderphanes are obtained by sequential ring‐opening metathesis polymerization and Glaser oxidation of norbornene appended with bisalkyne moieties. Hydrolysis of these ladderphanes gives substituted poly(m‐phenylene butadiynylene)s with narrow polymer dispersity index (PDI) and well‐controlled degree of polymerization.
ROMP没什么:通过顺序开环易位聚合和降冰片烯与双炔烃部分连接的Glaser氧化获得不对称的双链梯形。这些ladderphanes的水解得到取代的聚(米亚苯基butadiynylene)■具有窄分散度聚合物指数(PDI)和聚合的良好控制的程度。
