Used as a versatile building block in metal-organic frameworks (MOFs), enabling applications in gas storage, separation, and catalysis due to its rigid triangular structure and multiple coordination sites. Its pyrazole groups readily bind to metal ions, forming porous and stable networks. Also employed in the design of luminescent sensors and porous materials for selective detection of small molecules and environmental pollutants. Shows promise in proton-conducting materials for fuel cell applications when incorporated into coordination polymers.
