Figure 1: Bond-selective electron-induced reaction of physisorbed mDIB on Cu(110).
From: Bond selectivity in electron-induced reaction due to directed recoil on an anisotropic substrate
STM images (EXPT) and simulations (TH) show the selective dissociation of the C-I bond. (a) An intact physisorbed mDIB. The white cross indicates the midpoint of mDIB in the STM image. The two C-I bond directions, ‘AL’ and ‘AC’, are given by blue lines and designated as C-I(AL) and C-I(AC). (b) A reactive outcome as a result of the breaking of C-I(AL) in the prior mDIB reagent. (c) A reactive outcome for the single observed case of mDIB breaking C-I(AC). In the pictured final states (PIC), the green dashed circle indicates the Cu atom to which the IPh was bound, and the blue dashed line the direction of the broken C-I bond. All experimental STM images shown here are 25 × 17 Å2 in size, recorded at a sample bias of +0.1 V and a tunnelling current of 0.1 nA.
