We present a new efficient two-step method to covalently functionalize hydride terminated silicon nanocrystals with nucleophiles. First a reactive chlorosilane layer was formed via diazonium salt initiated hydrosilylation of chlorodimethyl(vinyl)silane which was then reacted with alcohols, silanols and organolithium reagents. With organolithium compounds a side reaction is observed in which a direct functionalization of the silicon surface takes place.
我们提出了一种新的高效两步法，用于用亲核试剂对氢化物封端的硅纳米晶体进行共价功能化。首先，通过重氮盐引发的氯二甲基（乙烯基）硅烷的硅氢化反应形成反应性氯硅烷层，然后使其与醇、硅醇和有机锂试剂反应。对于有机锂化合物，观察到一种副反应，其中硅表面发生直接功能化。
