How to control the inner motions of molecules: from photoswitches to molecular machines

Hemithioindigo (HTI) dyes are a class of emerging photoswitches [1] with many advantages compared to the most commonly used stilbenes, azobenzenes, or dithienylethenes. However, despite their high potential as versatile and efficient molecular triggering unit, they have been largely overlooked by material sciences as well as supramolecular and biological chemistry. In the recent years, we have explored the interesting photophysical properties of HTIs in depth and developed a thorough mechanistic understanding of their light induced motions and behavior in the excited state. [2] This brings us in the position to tailor unusual and useful property profiles, i.e. combinations of certain properties, by using strategic substitutions at the core structure of HTI.

We use this fundamental knowledge to build next generation molecular machines [3] and responsive supramolecular systems [4] with unprecedented properties. Our main goal is to develop smart molecular entities, [5] which can conveniently be implemented into more complex architectures to manipulate matter at the molecular scale with the highest possible precision. Key issues that we address are a complete control over the mechanics of molecular motions and the interactions between different molecular entities using nondestructive visible light.
