Diaryliodonium salts were found to initiate hydrosilylation reactions on the surface of silicon nanosheets as well as silicon nanocrystals of different sizes. A variety of different functional substrates can be used to stabilize the surface of the photoluminescent materials. Additionally, the combination of hydride terminated silicon nanomaterials with diaryliodonium salts was found to initiate cationic ring opening polymerization, demonstrating the potential of silicon based nanomaterials as coinitiators and enabling a mild, straightforward reaction method.
二芳基碘鎓盐被发现可以在硅纳米片以及不同尺寸的硅纳米晶的表面引发硅氢加成反应。多种不同功能的基底可以用来稳定发光材料的表面。此外，氢终止的硅纳米材料与二芳基碘鎓盐的组合被发现可以引发阳离子开环聚合，这表明了基于硅的纳米材料作为共引发剂的潜力，并使温和、直接的反应方法成为可能。
