Confining perovskite quantum dots in the pores of a covalent-organic framework: quantum confinement- and passivation-enhanced light-harvesting and photocatalysis

Monodisperse CsPbX 3 (X = Cl, Br, I) perovskite quantum dots (QDs) were encapsulated into the ordered mesopores of a thiol-functionalized covalent-organic framework (COF-SH) to construct highly efficient artificial light-harvesting systems.
