“…Metal-organic frameworks (MOFs), also known as porous coordination polymers (PCPs) have attracted many chemists' interest owing to their fascinating structural topologies and potentials in functional applications [1], such as molecular filter, gas storage [2,3], energy storage [4] and luminescent sensor [5,6]. Among the various kinds of MOFs, Lanthanide metal-organic frameworks (Ln-MOFs) as sensing materials for pollutant detection, such as poisonous gases, organic solvents, and heavy metals, have recently received increasing attention because of the advantages of short response time and high sensitivity towards specific analytes [7].…”
