Photo-controllable heterostructured crystals of metal-organic frameworks via reversible photocycloaddition.

ABSTRACT: Metal-organic framework (MOF)-based heterostructures are attractive because they can provide versatile platforms for various applications but are limited by complex liquid epitaxial growth methods. Here, we employ photolithography to fabricate and control MOF-based heterostructured crystals via [4 + 4] photocycloaddition. A layered dysprosium-dianthracene framework, [Dy(NO₃)₃(depma₂)_1.5]·(depma₂)_0.5 (2) [depma₂ = pre-photodimerized 9-diethylphosphonomethylanthracene (depma)] underwent a single-crystal-to-single-crystal transition at 140 °C to form [Dy(NO₃)₃(depma)(depma₂)]·(depma₂)_0.5 (3). The dissociated anthracene moieties are face-to-face π-π interac
