Summary: This article introduces a new technique called microfluidic-assisted solution shearing combined with post-synthetic rapid crystallization (MASS-PRC) process to fabricate high-quality, flexible, and transparent thin-film of Ni-3(hexaiminotriphenylene)(2). The process allows for large-area production with thickness control down to tens of nanometers, resulting in a film with high transparency and conductivity uniformity. The flexible thin-film demonstrates excellent transparency for Ni-3(HITP)(2) and the highest performance among c-MOFs-based H2S sensors, making it suitable for wearable gas-sensing applications.

Summary: This study immobilizes metal-organic framework (MOF) particles onto a gold substrate using spin coating, by using polymethyl (methacrylate) (PMMA) as a matrix for MOF materials. The PMMA films and MOF@PMMA films are investigated using surface plasmon resonance (SPR) spectroscopy to monitor their properties. The results demonstrate that the MOF/PMMA mixed films exhibit high response and selectivity towards haloalaknes.

Summary: Novel electrochromic hybrid thin films are synthesized using liquid-phase epitaxy to produce highly oriented surface-anchored metal-organic frameworks (SurMOFs). The orange color of the {Zn-2(PDICl4)(2)} crystalline thin films can be reversibly switched through electrochemical reduction. A dark blue color with a color efficiency of 104.8 cm(2) C-1 (lambda = 645 nm) can be achieved in a lithium-based electrolyte within seconds. The color of the reduced state can be easily modulated by changing the electrolyte composition. Additionally, electrochromic devices with a unique configuration have been designed to switch from an initial orange color to dark blue and cyan simultaneously.

Summary: In order to improve the performance of gas sensors and enhance the quality of life, the use of metal-organic frameworks (MOFs) as sensing materials has been explored. MOFs are known for their high surface area, porosity, and unique surface chemistry, making them promising for gas-sensor innovations. Various types of MOFs have been developed by studying their compositional and morphological dependences, and incorporating catalysts and light activation. Additionally, MOFs have multiple applications as molecular sieves, absorptive filtering layers, and heterogeneous catalysts due to their separation properties and catalytic activity.
