Photochemical modification of solid materials

摘要

The present invention relates to a process for modifying or functionalizing oxide surfaces, such as surfaces of SiO2 and Al2O3, but also metals including alloys such as stainless steel with alkenes or alkynes under mild conditions by photochemical reaction. The process is very well suited to form patterned modified surfaces which are of use for example in microelectronics, biosensing and catalysis.

1. A process for the modification of a solid material having a surface comprising hydroxyl-groups, said process comprising the step of contacting said solid material, under radiation with
(a) light of a wavelength in the range of 200 to less than 275 nm, or (b) light of a wavelength in the range of 300 to 800 nm in the presence of a photoinitiator, with a C2-C50 alkene, a C2-C50 alkyne, or both a C2-C50 alkene and a C2-C50 alkyne, the alkene and/or alkyne being linear or branched.
