Taming Molecules in Hybrid Nanosystems — •Jürgen P. Rabe — Department of Physics, Humboldt-Universität zu Berlin, Germany

Single molecules are precisely defined quantum objects, whose properties depend strongly on their immediate environment. Therefore hybrid nanosystems provide powerful means to control them. On the other hand, structure-property relationships of molecules in nanosystems are a key to understanding their function in biological systems and also to develop multi-functional artificial nanosystems. Here we report on the control over and with chain molecules and monoatomically thin crystals, i.e. quasi 1- and 2-dimensional macromolecules, which are highly flexible in solution while their conformation and their corresponding properties can be well defined in hybrid nanosystems. We have developed tools and platforms to correlate structure and dynamics in such systems with their properties. This includes ordered self-assembled monomolecular layers on an inert solid substrate, which can be used, e.g., to manipulate single macromolecules with scanning probes and light [1], a soft slit-pore from graphene and a solid substrate for ultrathin fluid films, which may serve as a nanoscopic test tube [2], and organic-inorganic hybrids based self-assembled molecular nanotubes with interesting opto-electronic and energy transfer properties [3].
