Abstract
Disclosed is a method of desorbing an adsorbed material by subjecting to energy a diazirine adsorbed on a solid surface or a layer on the solid surface, which causes the diazirine to form a carbene and nitrogen gas; and using the energy of the resultant nitrogen gas to desorb the adsorbed material from the solid surface or a layer on the same. Also disclosed is a method of reacting the resultant carbene with (a) a material in the gas phase proximal to the first solid surface; (b) a material adsorbed on a second solid surface proximal to the first solid surface; or (c) a second solid surface proximal to the first solid surface.
Claims20
A method of desorbing an adsorbed material, comprising the steps of:
- (i) providing a solid comprising a first solid surface on which a diazirine and a material are adsorbed;
- (ii) exposing the diazirine to a source of energy, thereby generating a carbene and nitrogen gas;
- wherein the nitrogen gas evolves from the first solid surface with sufficient energy to desorb the material from the first solid surface.
A method of reacting a carbene, comprising the steps of:
- (i) providing a solid comprising a first solid surface on which a diazirine is adsorbed;
- (ii) exposing the diazirine to a source of energy, thereby generating a carbene and nitrogen gas;
- wherein the nitrogen gas evolves from the first solid surface with sufficient energy to desorb the carbene from the first solid surface;
- and
- (iii) reacting the desorbed carbene with one of:
- (a) a material in the gas phase proximal to the first solid surface;
- (b) a material adsorbed on a second solid surface proximal to the first solid surface, wherein the second solid surface is comprised by the solid or a second solid;
- or
- (c) a second solid surface proximal to the first solid surface, wherein the second solid surface is comprised by the solid or a second solid.
