研究了钯催化的Suzuki、Heck和Sonogashira偶联反应作为硅表面有机修饰的反应方案。这些合成上有用的协议允许对烯烃、炔烃和卤化物端接表面进行表面改性。用X射线光电子能谱分析了表面氧化和金属污染情况。在二次功能化过程中，一次钝化层的性质是影响硅表面抗氧化性的重要因素。具体地说，与烯烃类似物相比，使用炔烃作为主要官能化层具有更好的稳定性。在硅表面利用钯催化的偶联化学的能力为潜在的分子和纳米级电子学和传感/生物传感应用打开了巨大的多样性。
Palladium-catalyzed Suzuki, Heck, and Sonogashira coupling reactions were studied as reaction protocols for organic modification of Si surfaces. These synthetically useful protocols allow for surface modification of alkene, alkyne, and halide terminated surfaces. Surface oxidation and metal contamination were assessed by X-ray photoelectron spectroscopy. The nature of the primary passivation layer was an important factor in the oxidation resistance of the Si surface during the secondary functionalization. Specifically, the use of alkynes as the primary functionalization layer gave superior stability compared to alkene analogues. The ability to utilize Pd-catalyzed coupling chemistries on Si surfaces opens great versatility for potential molecular and nanoscale electronics and sensing/biosensing applications.
