However, the toxicity and reactivity of the spent chromophore, o-nitrosobenzaldehyde, remains an unaddressed difficulty. In this study we have applied the well-established supramolecular photochemical concepts to retain the spent trigger o-nitrosobenzaldehyde within the organic capsule after release of water-soluble acids and alcohols. The sequestering power of organic capsules for spent chromophores during photorelease from ortho-nitrobenzyl esters, ethers and alcohols is demonstrated with several examples.engPhotoremovable protecting groupsReaction-Mechanisms2-Nitrobenzyl compoundsGuest moleculesCapsuleplexPhotoreleaseContainersSystemEstersWaterSupramolecular photochemistry of encapsulated caged ortho-nitrobenzyl triggersjournal article10.1039/c9pp00260j
