Fabrication of 3D Oriented MOF Micropatterns with Anisotropic Fluorescent Properties (Adv. Mater. 25/2023)

Micropatterning In article number 2211478, Christian Doonan, Paolo Falcaro, and co-workers describe the fabrication of oriented metal–organic framework (MOF) micropatterns with anisotropic optical properties. A mixed-linker strategy is used to impart X-ray sensitivity, while heteroepitaxial growth affords the orientation of MOF crystals. The 3D-oriented MOF films are patterned by resist-free X-ray photolithography. The MOF micropatterns with immobilized guest-molecules showcase fluorescence anisotropy.
