Resumen:
Charge transfer from an adsorbed molecule to a metal surface induces an in-plane dipole moment that is strong enough to drive self-assembly. The STM image shows a styrene tetramer adsorbed on Ag(100). The dipole moment of styrene changes from 0.15 D in the gaseous state to 1.12 D in the adsorbed state. This substrate-induced dipole amplification is crucial to increasing the intermolecular interaction energy.
