Metal organic frameworks (MOFs) are 3D inorganic-organic porous materials built from secondary inorganic clusters linked by polydentate organic moieties. Carboxylate ligands such as 1,3,5-benzenetricarboxylic acid (BTC) and 1,4-benzenedicarboxylic acid (BDC), are commonly employed as linkers due to their coordination ability with transition metals and trivalent rare earth ions, and their ability to form more rigid frameworks by facilitating the aggregation of metal ions into M-O-C molecular units. Despite of the increasing community’s interest in MOFs, the immobilization of MOFs on flexible solid supports is in its infancy. This presentation will focus on the in situ growth of a series of lanthanide metal organic frameworks, <b>Ln-MOFs</b> (Ln=Eu, Gd, and Tb) on cotton fibers using a room temperature water-based direct precipitation technique. This synthesis protocol enables effective crystallization of high loading of Ln-MOFs on natural fibers. MOF crystals were found to be well attached to the cotton fibers while maintaining their crystal structure. Intense emissions of red, blue, and green at room temperature, under UVC exposure was observed for Eu, Gd, and Tb MOFs, respectively.<br/>
