Photopatterning of fluorescent host–guest carriers through pore activation of metal–organic framework single crystals

Abstract

Encoded fluorescent particles are fabricated through the selective uptake of dyes in photopatterned metal–organic framework single crystals. The concept is based on spatially controlled photochemical cleavage of pore-blocking pendant groups. Because of the crystalline and porous nature of the host, this approach enables guest uptake that is tunable and can be triggered though controlled irradiation.
