Before Hermann Staudinger publishe d the brilliant concept of macromolecules\, it was generally assumed that the properties of polymers were based on the colloidal aggregation of smal l particles or molecules. Since 1920\, polymers and macromolecules have be en synonymous with each other\; i.e. materials made by many covalent bonds connecting monomers in 2 or 3 dimensions. Although supramolecular interac tions between macromolecular chains are evidently important\, e.g. in nylo ns\, it was unheard of proposing polymeric materials based on the interact ion of small molecules. Breakthroughs in supramolecular chemistry have sho wn that polymer materials can be made by small molecules using strong dire ctional secondary interactions\; the field of supramolecular polymers emer ged. In a sense\, we have come full circle [1]. Many of the concepts of ma cromolecular polymers apply to supramolecular polymers\, with only one imp ortant difference with fascinating consequences: the dynamic nature of the bonds that form polymer chains. This concept created the field of supramo lecular materials\, where novel unexpected properties are discovered. By c ontrolling supramolecular interactions between molecular fragments\, it be came easier to design materials with unconventional responsive behavior an d dynamic functionalities. In all cases\, control over the position of the molecules in time and space is key to arrive at the required functionalit y. Different supramolecular approaches and selected external stimuli will be discussed in the lecture\, with special emphasis on supramolecular mate rials with\, on the one hand\, highly ordered morphologies that will chang e their properties on the action of light\, pressure\, temperature\, or th e addition of chemicals. On the other hand\, applications in spin filterin g\, biomaterials and OLEDs will be discussed.\n\n \n\nBio:\n\nE.W. “Bert” Meijer is Distinguished University Professor in the Molecular Sciences\, P rofessor of Organic Chemistry at the Eindhoven University of Technology\, and co-director of the Institute for Complex Molecular Systems.
