A DFT Study of the 1,3-Dipolar Cycloadditions on the C(100)-2 × 1 Surface

Abstract

The 1,3-dipolar cycloadditions (1,3-DCs) of a series of 1,3-dipolar molecules onto the C(100)-2 x 1 surface have been investigated by means of hybrid density functional B3LYP method in combination with cluster model approach. It was found that 1,3-DCs on the C(100)-2 x 1 surface are more favorable over their molecular analogues both thermodynamically and kinetically. The enhancement of the reactivity on the surface due to the reduced overlap between the p(pi) orbitals of the surface C=C dimer should be important for the semiconductor industry because it might lead to a breakthrough in the fabrication of diamond films at low temperature.
