Surface science studies of polymers surfaces are surprisingly limited despite the increasing application of polymers in biomedicine and polymer device electronics, yet efforts are underway to address this deficiency. At the microscopic scale, we find that dipole interactions matter and affect the surface chemistry at various polymer and organic layer surfaces � it is in fact possible to alter the surface termination of an organic by application of a voltage and in turn use this type of surface manipulation to enhance or suppress the adsorption chemistry of some molecular adsorbates. The role of the frontier orbital symmetry is also seen to be very important and in some cases more important than the dipolar interactions. The interface dipole interactions may also affect organic device properties: generally, the manipulation of interface dipoles can be exploited to fabricate novel organic electric devices with some rather novel properties, as will be demonstrated.
