The design and application of dissipative supramolecular materials.

Séminaire du Dr Job Boekhoven (Technical University of Munich)

Abstract :

Why can’t we make materials like biology does? A car tire that regenerates itself like our skin does; Or a sweater that adapts to the cold like the hairs on our skin. Besides the obvious “biology is complex”, there is a trivial answer: most biological materials exist in states far away from equilibrium where processes like adaptation and regeneration are regulated by chemical reactions. Most synthetic materials, on the other hand, exist in- or close-to equilibrium.

 

We have thus set out to explore the design and use of dissipative non-equilibrium self-assembly for the use of supramolecular materials.[1-3] In this work, I will discuss design criteria for such dissipative supramolecular materials. I will focus on our recently described chemistry that can be applied as a self-regulating ink, a time-controlled hydrogel and a material that can control cellular uptake as well as deliver drugs.
