Hybrid vesicles of pillar[5]arene/silica: Host-guest complexation and application in pH-triggered release

Pillar[5]arene/silica hybrid vesicles were constructed based on the amphiphilic and rigid properties of pillararenes, as well as the catalytic hydrolysis of tetraethoxysilane. Such vesicles integrated the high strength of silica and unique molecular recognition of pillararenes, both of which could tune the pH-triggered release behavior.
