(a) Anthracene-functionalized hydroxyethyl cellulose and CB[8]; and (b) schematic representation of the formation of homoternary complexes by accommodating two anthracene moieties in the cavity of CB[8]. (c) Schematic representation of the microcapsules generation using a charged surfactant within the carrier phase of oil, while CB[8] and anthracene functionalized HEC are dispersed in the water phase. (d) Laser-scanning confocal fluorescence image of microdroplets, confirming that Ant-HEC is localized at the microdroplet interface; (e) normalized distribution of microdroplet diameters, exhibiting a narrow size distribution (coefficient of variation 1.5%). (f) Scanning electron microscopy (SEM) image of dried microcapsules. (g) Brightfield micrographs of the microcapsule drying process, resulting in a collapsed structure (scale bars: 20 μm).
