DESCRIPTION:Prof. Bert Meijer\, Eindhoven University of Technology\, The N
 etherlands\nEver since the first polymers were discovered\, scientists hav
 e debated their structures. Before Hermann Staudinger published the brilli
 ant concept of macromolecules\, it was generally assumed that the properti
 es of polymers were based on the colloidal aggregation of small particles 
 or molecules. Since 1920\, polymers and macromolecules have been synonymou
 s with each other\; i.e. materials made by many covalent bonds connecting 
 monomers in 2 or 3 dimensions. Although supramolecular interactions betwee
 n macromolecular chains are evidently important\, e.g. in nylons\, it was 
 unheard of proposing polymeric materials based on the interaction of small
  molecules. Breakthroughs in supramolecular chemistry have shown that poly
 mer materials can be made by small molecules using strong directional seco
 ndary interactions\; the field of supramolecular polymers emerged. In a se
 nse\, we have come full circle [1]. Many of the concepts of macromolecular
  polymers apply to supramolecular polymers\, with only one important diffe
 rence with fascinating consequences: the dynamic nature of the bonds that 
 form polymer chains. This concept created the field of supramolecular mate
 rials\, where novel unexpected properties are discovered. By controlling s
 upramolecular interactions between molecular fragments\, it became easier 
 to design materials with unconventional responsive behavior and dynamic fu
 nctionalities. In all cases\, control over the position of the molecules i
 n time and space is key to arrive at the required functionality. Different
  supramolecular approaches and selected external stimuli will be discussed
  in the lecture\, with special emphasis on supramolecular materials with\,
  on the one hand\, highly ordered morphologies that will change their prop
 erties on the action of light\, pressure\, temperature\, or the addition o
 f chemicals. On the other hand\, applications in spin filtering\, biomater
 ials and OLEDs will be discussed.\n\nBio: E.W. “Bert” Meijer is Distin
 guished University Professor in the Molecular Sciences\, Professor of Orga
 nic Chemistry at the Eindhoven University of Technology\, and co-director 
 of the Institute for Complex Molecular Systems. After receiving his PhD de
 gree at the University of Groningen with Hans Wynberg\, he worked for 10 y
 ears in industry (Philips and DSM). In 1991 he was appointed in Eindhoven\
 , while in the meantime he has part-time positions at MPI-Mainz\, UC Santa
  Barbara\, and UNSW Sydney. Bert Meijer is a member of many editorial advi
 sory boards\, including Advanced Materials and is associate editor of the 
 Journal of the American Chemical Society. Bert Meijer has received several
  awards\, including the Spinoza Award (2001)\, the ACS Award for Polymer C
 hemistry (2006)\, the AkzoNobel Science Award (2010)\, the Cope Scholar Aw
 ard of the ACS (2012)\, the Prelog Medal (2014)\, the Nagoya Gold Medal (2
 017)\, the Chirality Medal (2018) the Hermann Staudinger Award (2022) and 
 the Grand Prix in Paris (2024). In 2020 he is knighted by the king to be C
 ommander in the Order of the Netherlands Lion. He is an honorable member o
 f several academies and societies\, including the US National Academy of S
 ciences and the Royal Netherlands Academy of Science\, where he is appoint
 ed to Academy Professor in 2014.
