The first PFS-fr/ock-polymethacrylate copolymer was reported in 2002 28 The procedure involved a two-step anionic polymerization (Scheme 3.7). Hydroxy terminated polyferrocenylsi-lane (PFS-OH) was initially synthesized using r-butyldimethylsilyloxy-1-propyllithium as an initiator bearing a protected alcohol functionality. Once isolated, PFS-OH was deprotonated using potassium hydride to afford the alkoxy chain end that initiates dimethylaminoethyl methacrylate (DMAEMA) for anionic polymerization. The PFS- -PDMAEMA block copolymer was obtained in a high yield (Mn = 11,000 PDI =1.3) and with a low polyferrocenylsilane content (PFS PDMAEM A = 1 5). [Pg.141]

Polyferrocenylsilane block copolymers also phase separate in solid state to generate periodic, nanoscopic iron-rich domains that can be observed by TEM without resorting to staining techniques.24 This bulk self-assembly behavior has been studied with various block copolymers, such as PS-fe-PFS,24,52 PI-h-PFS,49 and PFS-b-PMMA.22 Additional self-assembly complications...
