in a provisional LCD. It will be a requirement for future applications
that the structure and periodicity of the patterns is under full
control, e.g., by applying sheer force [19], external electric [20-21]
or magnetic [22] fields, or by localized heating of the surface during
the solvent evaporation process. When such control can be achieved,
the self-assembly/dewetting technique might open ways to new
applications for which surface-invasive techniques like rubbing,
scratching, or grafting are undesired. One can also consider applying
the technique in conjunction with conventional (photo-)lithographic
techniques [23] or stamping methods [24]. By doing so, many new
approaches towards applications in the areas of sensor development
and molecular electronics can be foreseen.
