The covalent attachment of organic moieties to silicon surfaces allows for a significant extension of the use of silicon as substrate in optoelectronic elements. Standard methods to obtain covalently attached monolayers to well-defined silicon surfaces include heating in neat alkene or in refluxing mesitylene, ultraviolet irradiation and Grignard reactions. A relative mild procedure for the functionalization of well-defined hydrogen terminated silicon surfaces using visible light is also reported which are compatible with bioactive moieties. This procedure yields water contact angles for alkyl monolayers derived from C[sub12]-C[sub16] alkenes and alkynes that are at least as high as previously reported using thermal methods. The attachment of saccharides to silicon surfaces opens up new routes to the detection of selective recognition of antibodies to oligosaccharide receptors.
