“…For the first time, Zhuang et al used inkjet printing technique to fabricate MOF thin films on various substrates by printing the precursor solution followed by drying. 34 Luz et al printed photoluminescent lanthanide-organic frameworks onto plastic and paper foils for anti-counterfeit applications. 35 However, both studies inkjet printed precursor solutions and an additional curing or post-processing step was required to obtain the patterned MOF thin films; such processes strongly restrict the types of MOFs that can be printed.…”

In this study, a simple and effective direct inkjet printing method was developed to prepare porphyrinic metal-organic framework (MOF) thin films for electrocatalysis. First, crystals of a zirconium-based porphyrinic MOF (MOF-525) with crystal sizes ranging from 100 to 700 nm were synthesized by adjusting the content of benzoic acid in the solvothermal synthetic process. The synthesized crystals showed similar surface area of 2500 m 2 /g with a unique pore size of 1.85 nm. However, some structural defects was found in the smallest crystals of 100 nm due to the fast crystallization process. After suspended in dimethylformamide, the MOF crystal suspensions were inkjet printed to fabricate uniform MOF-525 thin film patterns. With the help of great precision in liquid deposition, thicknesses of the printed MOF-525 thin films can be accurately controlled by the number of printed layers. With smaller crystal size, the printed MOF thin films showed more compact stacking and better contact with the substrate. The printed MOF thin films were applied for electrocatalytic nitrite oxidation. The effects of both film thickness and crystal size on printed film morphology and electrocatalytic activity were investigated in details. The printed MOF nitrite sensor showed a great detection limit of 0.72 μM and a high sensitivity of 40.6 μA/mM-cm 2 . In summary, this study demonstrated the feasibility of the proposed printing process for electrochemically addressable MOF thin films and can be further applied for many other electrochemical applications.

“…Having validated our model on PMMA, we next measure HKUST-1 30 microcrystals (Fig 4) obtained directly on the ZnSe prism by adapting an ink-jet printing method 31 . The measured τ s ( z ) values are well described by equation 5 (Fig 4C) and using HKUST-1 known C p and ρ (table S1) we estimate η HKUST-1 = 0.26 W·m −1 ·K −1 ± 0.02 W·m −1 ·K −1 at RH = 1.8 % ± 0.3 % (Fig.…”

Nanophotonic Atomic Force Microscope Transducers Enable Chemical Composition and Thermal Conductivity Measurements at the Nanoscale

The atomic force microscope (AFM) offers a rich observation window on the nanoscale, yet many dynamic phenomena are too fast and too weak for direct AFM detection. Integrated cavity-optomechanics is revolutionizing micromechanical sensing; however, it has not yet impacted AFM. Here, we make a groundbreaking advance by fabricating picogram-scale probes integrated with photonic resonators, to realize functional AFM detection that achieve high temporal resolution (< 10 ns) and picometer vertical displacement uncertainty, simultaneously. The ability to capture fast events with high precision is leveraged to measure the thermal conductivity (η), for the first time, concurrently with chemical composition at the nanoscale in photothermal induced resonance experiments. The intrinsic η of metal-organic-framework individual microcrystals, not measurable by macroscale techniques, is obtained with a small measurement uncertainty (8 %). The improved sensitivity (50×) increases the measurement throughput 2500-fold and enables chemical composition measurement of molecular-monolayer-thin samples. Our paradigm-shifting photonic readout for small probes breaks the common tradeoff between AFM measurement precision and ability to capture transient events, thus transforming the ability to observe nanoscale dynamics in materials.
