在这里，我们提出了自由基诱导的硅氢化反应的功能化的独立的硅纳米片（SiNS）。通过热引发或重氮盐与各种烯烃或炔烃衍生物的加成，可以实现SiH封端的SiNS的有效硅氢加成。自由基诱导的硅氢加成反应适用于各种具有不同功能的基底，提高了功能性SiNS在有机溶剂中的稳定性和分散性，并可能为这些杂化材料开辟新的应用领域。
Herein we present the functionalization of freestanding silicon nanosheets (SiNSs) by radical-induced hydrosilylation reactions. An efficient hydrosilylation of Si H terminated SiNSs can be achieved by thermal initiation or the addition of diazonium salts with a variety of alkene or alkyne derivatives. The radical-induced hydrosilylation is applicable for a wide variety of substrates with different functionalities, improving the stability and dispersibility of the functional SiNSs in organic solvents and potentially opening up new fields of application for these hybrid materials.
