報告內(nèi)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.
