Luminescent Functional Metal-Organic Frameworks

A comprehensive overview of the different types of luminescent Metal-Organic frameworks (MOF), particularly those with interesting and important applications, is presented. Studies have found that efficient lanthanide-centered luminescence of MOFs is fulfilled by the use of antenna organic linkers, and it is necessary that the lowest triplet state of the organic linkers is located at an energy level nearly equal to or above the resonance level of the lanthanide ion. Sun et al. prepared a series of Ln-Cd HMOFs that display 1D helical channels occupied by water molecules and SO 4 2- anions and helical tubes constructed from three distinct helical chains. Xu et al. also discussed and explained the possible sensing mechanism by the matching degree of TbNTA-3H 2O with different anions. Harbuzaru et al. reported a new MOF named ITQMOF-1-Eu with 4,40-(hexafluoroisopropylidene)bis(benzoicacid) as ligand, which crystallizes in long needles that can be handled individually.
