Here, we report a novel surface modification for porous silicon (pSi). Hydroxyl-terminated pSi surfaces are modified with a hydrosilane via Si-H activation using the Lewis acid catalyst tris(pentafluorophenyl) borane. This surface reaction is fast and efficient at room temperature, and leads to a surface stabilised against hydrolytic attack in aqueous media. The resulting surface shows promise as a substrate for surface-assisted laser desorption/ionisation mass spectrometry.
在此，我们报道了一种用于多孔硅（pSi）的新型表面改性方法。通过使用路易斯酸催化剂三（五氟苯基）硼烷，经硅氢键活化，用硅烷对羟基封端的pSi表面进行改性。这种表面反应在室温下快速且高效，能使表面在水性介质中稳定抵抗水解侵蚀。所得表面有望作为表面辅助激光解吸/电离质谱的基底。
