Abstract
A new luminescent MOF were synthesized by solvothermal method based on 1,1,2,2-tetrakis(4-(pyridin-4-yl)phenyl)ethene (TPPE), with the molecular structure of [Zn2(TPPE)0.5(ndc)2]n (ndc = 1,4-Naphthalenedicarboxylic acid) (LMOF-1). The single crystal structure indicates that LMOF-1 stacks in a three-dimensional structure. The fluorescence test results indicate that LMOF-1 emits blue light with quantum yield at 37.93 %, due to ligand–ligand charge transfer. PXRD and TG analysis confirmed that LMOF-1 has good stability, and PXRD analysis after different solvent exchanges confirmed that LMOF-1 has good stability in water. The results of ion titration experiments show that Fe3+, CrO42−, and Cr2O72− have significant quenching effects on LMOF-1, and the detection limits are 3.83 × 10−6 M, 2.57 × 10−5 M, and 4.33 × 10−6 M, respectively. Indicating that LMOF-1 can serve as a multifunctional ion detector.
期刊介绍:
Inorganica Chimica Acta is an established international forum for all aspects of advanced Inorganic Chemistry. Original papers of high scientific level and interest are published in the form of Articles and Reviews.
Topics covered include:
• chemistry of the main group elements and the d- and f-block metals, including the synthesis, characterization and reactivity of coordination, organometallic, biomimetic, supramolecular coordination compounds, including associated computational studies;
• synthesis, physico-chemical properties, applications of molecule-based nano-scaled clusters and nanomaterials designed using the principles of coordination chemistry, as well as coordination polymers (CPs), metal-organic frameworks (MOFs), metal-organic polyhedra (MPOs);
• reaction mechanisms and physico-chemical investigations computational studies of metalloenzymes and their models;
• applications of inorganic compounds, metallodrugs and molecule-based materials.
Papers composed primarily of structural reports will typically not be considered for publication.
