In this study, we propose one kind of photo-responsive microcapsule based on the coumarin-modified shell. The coumarin group firstly reacts with pentaerythritol on a stoichiometric basis and then etherifies with the polymerizable isocyanate group to obtain the shell material. To stabilize the shell structure, we fabricate coumarin-modified microcapsules (CMMs) via interfacial polymerization and 365 nm ultraviolet light irradiation. The particle size and surface morphology of microcapsules are measured by scanning electron microscopy and optical microscopy. After ultraviolet irradiation, the shell of CMMs exhibits variable fluorescence as well as reversible crosslinking and cleavage due to the [2 + 2] cyclization reaction. By introducing the fluorescent dye 2-anilino-6-dibutylamino-3-methylfluoran (ODB-2) into microcapsules, the controlled release behavior of CMMs can be measured by fluorescence microscope and fluorescence spectrophotometer. The CMMs exhibit distinct “on” state and “off” state separately under different ultraviolet light, achieving ODB-2 release and trapping. This result leads to precise characterization of controlled release property, which will be of interest in switchable microcapsules for drug delivery system and information recording device.
