報告人簡介：
Dr. Dong obtained his B.S degree in Pharmacy from Zhejiang University in 2005, He earned a Ph.D. degree in Chemistry from Zhejiang University in 2012. He became the Humboldt and Postdoc at Freie University in Germany in 2016. And now, he is the Professor of Hunan University. His research areas include Supramolecular Chemistry and Material Science.
報告內容：
Although the concept of structural water that is bound inside hydrophobic pockets and helps stabilizing protein structures is well established, water has never found a similar role in supramolecular polymers so far. In this field, water is often used as the solvent without ever taking the role of a monomer itself that is incorporated in the supramolecular polymer structure. We for the first time report a low molecular weight monomer (LMWM), whose supramolecular polymerization is triggered by water molecules whose presence as co-monomers is essential to the polymerization process. The supramolecular polymeric material exhibits surprisingly strong adhesion to surfaces such as paper and glass. It can be used as a strong, water-activated glue, which exhibits temperature-dependent strength in an application-friendly temperature range between room temperature and 60 oC. It can thus be released at higher temperatures and reused many times without losing its performance.
