Abstract
Surface-initiated Kumada catalyst-transfer polycondensation of poly(9,9-dioctylfluorene) (PFO) was performed from organosilica microparticles that resulted in PFO brushes with densely grafted PFO chains with a significantly enhanced propensity to adopt planar and ordered conformations (beta-phase).
摘要
通过有机硅微粒子进行了表面引发的 Kumada 催化剂转移缩聚反应，得到了聚（9,9-二辛基芴）（PFO）刷，其具有密度接枝的 PFO 链，显著增强了其采用平面和有序构象（β 相）的倾向。
