Abstract

Springing the trap: Cyclodextrin‐covered mesoporous silica nanoparticles with photocleavable linkers exhibit photoinduced release characteristics and a sol–gel transition that is induced by molecular recognition (see picture). Upon exposure to UV light, the guest molecules were released from the pore by removal of the CD “gatekeeper”, which was linked on the surface of the silica nanoparticle through a photocleavable o‐nitrobenzyl ester moiety.magnified image

## Abstract **Drang nach draußen**: Mit Cyclodextrinen (CDs) an photochemisch spaltbaren Linkern beschichtete mesoporöse Siliciumoxidnanopartikel entlassen eingeschlossene Spezies unter Bestrahlung und gehen einen Sol‐Gel‐Übergang ein, der durch molekulare Erkennung ausgelöst wird (siehe Bild). Unt
