Two-dimensional template

In the second part of this Chapter the thickness of the organic layer under discussion is slightly increased and a closer look at recent developments of more complex surface-bonded systems involving polymers is outlined. Despite the introduction of flexible polymer chains, the surface coating should still be defined and uncontrolled heterogeneities minimized. Here, especially, polymer brush-type layers where self-assembled monolayers (SAMs) are used as two-dimensional template systems for the preparation of well-defined surface coatings will be subject of a more detailed discussion. 

Figure 3-3 shows a view of a typical model for an industrial plant. Errors in a plant layout are easily located when three-dimensional models are used, since the operations and construction engineers can immediately see errors which might have escaped notice on two-dimensional templates or blueprints. In addition to increasing the efficiency of a plant layout, models are very useful during plant construction and for instruction and orientation purposes after the plant is completed. 

We conclude that the diffraction pattern obtained is from the polypyrrole produced at the air-water interface. Further, that this monolayer is in fact dictated into a new crystalline organization, as growth and polymerization is initiated from a 1 1 3HDP to pyrrole two-dimensional template. In which the horizontal lattice is comprised of electroactive polypyrrole. Figure 2 illustrates a schematic of the proposed two-dimensional template polymerization. A continuation of this investigation next involved determining the effect of Incorporation of a bulky ferrocene moiety into the monolayer organization.

The definition of templates originates from coordination chemistry and supramolecular science. The more modem use of the term template describes a molecular entity that brings structures together in a manner which would not happen in a non-templated fashion. This will result in a specific interaction or selective chemical transformation. In most examples, the template will be incorporated, but this is not necessarily the case [1,2], Electrodes and their surfaces may also be considered as two-dimensional templates [3]. Since only the electrosynthetic aspects will be treated here, they are not part of this survey.
