Original Abstract

Charge-transport through organic materials is anisotropic in nature – control over its self-assembly therefore presents a viable pathway towards improved electronic properties. Self-assembled monolayers have been recently proven to be powerful-tools for this task as the first layer affects all of the subsequent deposition. This can completely change the materials topography and surface potential (i.e. its work-function). Herein, we study poly(3-adamantylmethylthiophene) (PMAT) at the dimer and dodecamer level. These short oligomers display an aromatic and an adamantyl-functionality, both of which can be used to guide subsequent self-assembly. The aromatic thiophene-subunits are expected to be the guiding moiety in the case of bare gold (Au(111)), while adamantyl-thiol treated gold directs towards a less disordered self-assembly pattern. Phenlythiol may, however result in a type of self-assembly in which the first layer deposited exposes an entirely adamantyl-based surface in turn, which leads to specific assembly-features.
