Host guest supramolecular chemistry
WebHerein, we demonstrate a new strategy for harnessing photon upconversion—supramolecular upconversion—based on host–guest chemistry. We have identified a box-like fluorescent tetracationic host incorporating a thiazolothiazole emitter, which can accommodate a guest-sensitizer, 5,15-diphenylporphyrin, inside its cavity, and … WebNov 17, 2024 · Host–guest based supramolecular assemblies, as constructed through non-covalent interactions, are highly dynamic in nature, and can be tuned easily using their responses to various external stimuli, providing a convenient approach to achieve excellent functional materials.
