Facile Monolayer Formation on SiO2 Surfaces via Organoboron Functionalities

摘要

Organoboron surface functionalities are widely used in the contexts of sensing, catalysis, chromatography, and surface doping, among others. Several studies have demonstrated the introduction of organoboron surface functionalities through attachment by molecular linking groups: the linker group with the organoboron moiety attached at one end undergoes a reaction at its other end to form a covalent bond to the surface. There are very few examples, however, of the modification of surfaces by the direct attachment of a boron functionality to the interface. The organoboron modification of oxides, such as silica nano-particles (SiO2 NPs) and Si/SiO2 interfaces, is attractive for a wide range of applications. Therefore, a facile method for the direct anchoring of organoboron functionalities to SiO2 surfaces is desirable.
