Special Issue Information

Dear Colleagues,

Metal–organic frameworks are a class of porous materials composed of metal ions or clusters connected by organic ligands. They exhibit diverse structures and properties, making them highly versatile for various applications, including gas storage and separation, catalysis, sensing, and drug delivery.

In this Special Issue, we welcome research articles or reviews that delve into the functional aspects of MOFs, particularly emphasizing the interactions between guest molecules (such as gases, solvents, or ions) and the host framework. The exploration of these interactions is crucial for understanding the sorption mechanisms and designing MOFs with tailored properties for specific applications.

Overall, this Special Issue will serve as a platform for researchers to exchange insights, present cutting-edge developments, and contribute to the advancement of functional metal–organic frameworks and their diverse applications in various fields.

Solid electrolyte materials with high structural stability and excellent proton conductivity (σ) have long been a popular and challenging research topic in the fuel cell field. This problem can be addressed because of the crystalline metal–organic frameworks’ (MOFs’) high structural stability, adjustable framework composition, and dense H-bonded networks. Herein, one highly stable Sr(II) MOF, {[Sr(H2tmidc)2(H2O)3]·4H2O}n (1) (H3tmidc = 2-(1H-tetrazolium-1-methylene)-1H-imidazole-4,5-dicarboxylic acid) was successfully fabricated, which was structurally characterized by single-crystal X-ray diffraction and electrochemically examined by the AC impedance determination. The results demonstrated that the σ of the compound manifested a positive dependence on temperature and humidity, and the optimal proton conductivity is as high as 1.22 × 10−2 S/cm under 100 °C and 98% relative humidity, which is at the forefront of reported MOFs with ultrahigh σ. The analysis of the proton conduction mechanism reveals that numerous tetrazolium groups, carboxyl groups, coordination, and crystallization water molecules in the framework are responsible for the high efficiency of proton transport. This work offers a fresh perspective on how to create novel crystalline proton conductive materials. Full article
