Several carbosilane wedges of generations 1–3 have been synthesized, following the divergent method, containing at the focal point a C–Br bond and as peripheral functional groups SiMeCl2, SiMe(C3H5)2, SiMe2Cl, SiMe2H, and ester units SiMe2(C3H6)N(C2H4CO2Me)2}. The dendrons functionalized with SiMe(C3H5)2 and SiMe2(C3H6)N(C2H4CO2Me)2} groups were used to synthesize spherical dendrimers derived from
按照发散法,已经合成了1-3代的几个碳硅烷楔,在焦点处包含一个C-Br键,并作为外围官能团包括SiMeCl 2,SiMe(C 3 H 5)2,SiMe 2 Cl,SiMe 2 H和酯单元SiMe 2 (C 3 H 6)N(C 2 H 4 CO 2 Me)2 }。用SiMe(C 3 H 5)2和SiMe 2 (C 3 H 6)N(C 2使用H 4 CO 2 Me)2 }基团合成源自1,3,5-(HO)3 C 6 H 3的球形树枝状大分子,而外部基团保持不变。如此获得的烯丙基树枝状聚合物用作前体以制备用SiMeCl 2,SiMe 2 Cl,SiMe 2 H,胺单元SiMe 2 ((C 3 H 6)NH 2)和酯单元SiMe 2 (C 3) H 6)N(C 2 H 4 CO 2 Me)2}。
