Electrical bias dependent photochemical functionalization of diamond surfaces

Article Abstract:

The effect of applying an electrical bias to the diamond samples during the photochemical reaction is examined in order to develop a better understanding of the photochemical reaction mechanism. The bias-dependent changes in rate are attributed to a field effect, in which the applied potential induces a strong downward band-bending on the negative electrode and facilitates the ejection of electrons into the adjacent fluid of reactant organic alkenes.

Photochemical functionalization of hydrogen-terminated diamond surfaces: A structural and mechanistic study

Article Abstract:

The structure and mechanism of the photochemical modification of diamond with functionalized terminal alkenes are investigated. The results indicate that the functionalization is a surface-mediated photochemical reaction and suggest that modification is initiated by the photoejection of electrons from the diamond surfaces into the liquid phase.

Density functional theory investigation of product distribution following reaction of acrylonitrile on diamond (001)-2x1 surface

Article Abstract:

Density functional cluster model computations are applied to the study the reaction of acrylonitrile with the C (001)-2x1 surfaceof diamond. It is shown that isomerization between the intradimer [4+2] product and intradimer [2+2] (sub cc) product is little more suitable than the direct path to formation of the intradimer [2+2] (sub cc) product.
