“…Nowadays, coordination polymers (CPs), as one class of promising functional materials, have received widespread attention not only due to unique topologies, such as multiple active sites, modifiable channels and fascinating architectures, but also due to excellent performance and potential applications in various fields, such as catalyst carrier, proton conducting, sensing, magnetic and fluorescent materials, gas separation and storage [ 1 , 2 , 3 , 4 , 5 , 6 , 7 , 8 ]. In particular, the structural diversity and multi-functional characteristics of CPs aroused intense interest in the design and construction of chemical sensing materials [ 9 , 10 , 11 , 12 ].…”
