“…The luminescent properties of these codoped MOFs materials can be tuned by adjusting the ion ratios, creating hybrid systems with synergistic properties [28,29]. Additionally, MOFs can form interpenetrated structures, consisting of intertwined frameworks that enhance charge transport sensitivity [20,30].…”

Tbx-Zn1-x-BDC MOF films were deposited in-situ on glass substrates by the aerosol-assisted chemical vapor deposition technique (AACVD) using an ultrasonic spray pyrolysis system, with x in the range of 0 to 1. Different precursors and solvents were used for the precursor solutions, which were deposited on a substrate using a controlled nebulization system. The obtained films were characterized using techniques, such as X-ray diffraction, Raman spectroscopy, Fourier transform infrared spectroscopy (FTIR) and photoluminescence spectroscopy. The results revealed the evolution of the Zn-BDC and/or Tb-BDC crystalline structures in the films, as well as the changes in the physical properties of the Metal-organic frameworks (MOFs) such as thickness and roughness of the films. Furthermore, these findings provide important information for the design and control of MOF films with specific properties and their potential application in various fields.

The niobium metal–organic framework (Nb‐MOF = [Nb2(bdc)2(NDI)]n) membrane, constructed from terephthalic acid(bdc) and 1,8,4,5‐naphthalenetetracarboxdiimide (NDI), is in this work grown on the surface of lithium niobate (LiNbO3) film composite optical waveguide (COWG) substrate using UV‐light illumination method. After growing for 20 min, the Nb‐MOF membrane forms as a graphene‐like structure with 50 nm pore size and 96 nm thickness. At room temperature (25 °C), in terms of COWG sensors, Nb‐MOF exhibits the greatest response to H2S and SO2, followed by ethylenediamine (EDA) and NO2, coexistence with 15 kinds of benzenes, amines, and acidic gases. In order to improve its response selectivity, the spirooxazine (SP) is embedded into the Nb‐MOF frame, and a SP@Nb‐MOF membrane COWG with smooth‐snowflake imprinted surface is obtained. In gas sensing performance, the obtained COWG shows the greatest response to H2S, while the response of SO2, NO2, and other gases are obviously diminished. When the SP@Nb‐MOF membrane exposes to H2S gas, proton‐transfer and morphology modulation are induced. The presented sensor also shows a wide detection range (1 × 104–0.1 ppb), fast response (4 s), and long‐term stability of 120 d to H2S at room temperature (25 °C) and 25% relative humidity.

Optical switching materials that respond to external stimuli including acidity/alkalinity, redox conditions, temperature, and guest molecules are extremely desirable. This paper reports hydrogen‐bonded organic framework (HOF) films with structure‐dependent optical switching properties in the presence of acidic/alkaline gases. A series of TPPS‐[(bdc)2‐(BIPA‐TC)]n‐HOF films, constructed from terephthalic acid, benzoimidephenanthroline tetracarboxylic acid, and phenylporphyrin sulfonate, were prepared on the surface of a LiNbO3 film composite optical waveguide (COWG) substrate using the solgel method. Upon increasing the drying temperature from 90 to 160 °C, the BIPA‐TC‐HOF‐x film structure evolved from flatter porous to a birds‐nest, and subsequently to a granular structure. The hostguest interactions between the BIPA‐TC‐HOF and the analyte gases induced different degrees of switching in terms of the refractive index. Gas sensing selectivity of the HOF‐x film COWG progressed from EDA sensing to EDA and H2S co‐sensing, and finally to H2S without any interference from the other acid/base gases. This phenomenon was attributed to the variations in the acidity/alkalinity of the BIPA‐TC‐HOF caused by structural changes during the drying process. The gas adsorption kinetics were found to be consistent with Pseudo‐Second‐Order kinetic model. This work provides a novel approach for the development of optic switching sensors.
