Mesoporöse Siliciumdioxid‐Nanopartikel wurden mit einem Photosäuregenerator und Gastmolekülen beladen und mit einer Schale aus Gerbsäure und CuII‐Ionen ummantelt. In der Zuschrift auf S. 5577 ff. beschreiben C. Park et al. eine schnelle und einfache Methode für die Herstellung solcher photoresponsiver Nanocontainer und verschiedener Hybridstrukturen, wie Dünnfilme und adaptive Hydrogele. Dieser neue...
The coordination chemistry of plant polyphenols and metal ions can be used for coating various substrates and for creating modular superstructures. We herein explored this chemistry for the controlled release of guests from mesoporous silica nanoparticles (MSNs). The selective adsorption of tannic acids (TAs) on MSN silica walls opens the MSN mesoporous channels without disturbing mass transport....
