In 1989 he moved to DSM Research in Geleen to become head of the department for New Materials. In 1991 Meijer was installed as full professor of Organic Chemistry at the department for Chemistry & Chemical Engineering of Eindhoven University of Technology (TU/e) and in 1999 at the department for Biomedical Engineering at the same university. Since 2004 Bert Meijer is a distinguished university professor of Molecular Sciences at TU/e, where he founded the Institute for Complex Molecular Systems and served as its Scientific Director from 2008 until 2018. Meijer is adjunct professor of Macromolecular Chemistry at Radboud University Nijmegen since 1994 and distinguished visiting professor at the University of California, Santa Barbara since 2008. In 2014 Bert Meijer was inducted as Academy Professor of the Royal Netherlands Academy of Arts and Sciences.

## Contributions to research

Meijer's research focuses on supramolecular systems with special properties and functions. It's founded on the principles of synthetic and organic chemistry to find solutions to challenges in materials science and life sciences. Meijer is recognized as a pioneer in the field of supramolecular materials, being one of the first chemists to explore and develop functional supramolecular polymers as a new class of materials. Via advanced molecular design and synthesis he has realized systems in which monomeric units self-assemble into long supramolecular polymeric chains, resulting in materials displaying unique dynamic properties that were thought to be exclusively reserved for macromolecules. His new class of supramolecular structures thus led to an adjusted definition of Staudinger’s description of what polymers are.
Meijer's career took off with breakthrough results in dendrimer chemistry including a dendritic box and super-amphiphiles (being the first examples of polymersomes). He synthesized poly(propylene imine) dendrimers that are now produced at commercially relevant quantities (at multiple kilogram scale) worldwide. His dendrimers form the basic compound of a phosphate binder currently used in the clinic. Meijer also developed novel semiconducting polymers with high electron mobilities. His exploration of the combination of chirality and mesoscopic morphology in these polymers led to the fabrication of an LED that emits circularly polarized light. Many years later the insights into chiral semiconductors were used to optimize the water splitting in a photoelectrochemical cell.
Meijer's discovery of ureidopyrimidinone-based supramolecular polymers is a landmark in supramolecular chemistry. He designed a simple quadruple hydrogen-bonded building block that is self-complementary and exhibits a very large association constant. Bringing two of these units together with a spacer resulted in a supramolecular polymer with unprecedented properties. Depending on the conditions applied it on the one hand it possess all the properties of macromolecules, both in solution and solid state, while on the other hand it displays the dynamic nature of organic molecules tied together via non-covalent bonds. Today, the concept of supramolecular polymers is investigated in many international academic and industrial laboratories. The Meijer lab has successfully started the company SupraPolix, offering a supramolecular polymer platform as a key component in several applications, including glue (as superflow elastomers), cosmetics and regenerative medicine of heart valves, for which clinical trials are underway by the Dutch/Swiss company Xeltis.
Following up on his discovery Meijer has unraveled the mechanisms behind chemical self-assembly and has proven that supramolecular polymerizations can be classified, based on their mechanism, in a way similar to conventional polymerizations. Current research in the Meijer lab focuses on complex multi-component supramolecular polymer systems and their assembly behaviour Also the potential use of supramolecular polymers is explored as mimics of biological tissue using a modular approach that allows for easy adjustment of their dynamics to external stimuli.
