3.8.5.1 Background

Anisotropic Assembly of Ag Nanoprisms

“…On Assembly A and B, the S 2p 3/2 binding energies are 161.7 and 159.6 eV, respectively (Figure S5). On the basis of the fact that thiol molecules generally adsorb at the highest coordination site on a given surface and thiol will have a greater S 2p binding energy if it is adsorbed at a higher coordination site, the observed greater binding energy on Assembly A indicates that the binding site of 4-ABT on Assembly A has a higher coordination number than on Assembly B. This is consistent with the fact that the highest coordination sites of Ag(100) and Ag(111) surfaces are 4-fold and 3-fold hollow sites, respectively …”
