Abstract

New zinc-based luminescent coordination polymer [Zn₂(bpy)(H₂O)₂(L_O)₂] (Zn-CP, H₂L_O – 4,7-di(4-carboxypyrazol-1-yl)-2,1,3-benzooxadiazole, bpy – 4,4′-bipyridine) was synthesized. The compound demonstrated high stability in various organic solvents and excellent luminescent properties with the photoluminescence quantum yield of 57 %. Zn-CP was capable of detecting aluminum, gallium and dihydrogen phosphate ions with the limits of detection 0.10, 0.17 and 0.14 μM, respectively. The luminescence turn-on upon the addition of these analytes can be detected by the naked eye, making possible the fabrication of express test paper strips. The possibility of using the CP as phosphors in UV-pumped light-emitting diodes was also demonstrated.

期刊介绍： Optical Materials has an open access mirror journal Optical Materials: X, sharing the same aims and scope, editorial team, submission system and rigorous peer review. The purpose of Optical Materials is to provide a means of communication and technology transfer between researchers who are interested in materials for potential device applications. The journal publishes original papers and review articles on the design, synthesis, characterisation and applications of optical materials. OPTICAL MATERIALS focuses on: • Optical Properties of Material Systems; • The Materials Aspects of Optical Phenomena; • The Materials Aspects of Devices and Applications. Authors can submit separate research elements describing their data to Data in Brief and methods to Methods X.
