- Synthesis of electron deficient acene derivatives via a bidirectional iterative elongation reaction
-
Previously, we developed an iterative elongation methodology to synthesize acene esters, nitriles, and imides. The strategy uses the concept of bidirectional synthesis, and we can now make a series of electron deficient anthracene, tetracene, and pentacen

- Novel cruciform structures as model compounds for coordination induced single molecule switches
-
We have synthesized various molecular cruciforms consisting of two different crossing π-systems and comprising crosswise arranged thiol- and pyridine-anchor groups. With these model compounds we strive towards the investigation of a new switching concept based on the potential dependent coordination of pyridines to gold electrodes in an electrochemical set-up. Integration of these cruciform molecules between both electrodes of a mechanically controlled break junction in a liquid environment gave insight into their single molecule transport properties. These studies allowed individual transport characteristics to be assigned to the bar subunits of the cruciforms but also revealed the remaining experimental challenges to realize the suggested switching concept.

- New cruciform structures: Toward coordination induced single molecule switches
-
(Chemical Equation Presented) New cruciform structures 1-4 were synthesized to investigate a new single molecule switching mechanism arising from the interplay between the molecule and the electrode surface. These molecular cruxes consist of two rod-type

- A supramolecular bundling approach toward the alignment of conjugated polymers
-
(Figure Presented) All line up together! A new concept for the alignment and assembly of conjugated polymers through the action of supramolecular bundling ("aligner") molecules is inspired by actin-filament bundling proteins. The approach provides a gener
