Two luminescent Zn(II) coordination complexes as fluorescence-responsive sensors for efficient detection of Cu2+ ions

Nanomaterials Based on Collaboration with Multiple Partners: Zn3Nb2O8 Doped with Eu3+ and/or Amino Substituted Porphyrin Incorporated in Silica Matrices for the Discoloration of Methyl Red

“…In this respect, researchers combined mixed oxides, porphyrins, and silica or polymeric materials [1] with the purpose of being used in field emission displays (FED) [2,3]. Especially as cathodoluminescent materials, as adsorbent materials [4][5][6], as sensitive materials for sensor devices [7,8], or as photocatalysts for dye degradation [9]. The properties of these materials depend on their morphology, size, specific surface area, composition, and conductivity.…”

Efficient emission of Zn(ii) and Cd(ii) complexes with nopinane-annelated 4,5-diazafluorene and 4,5-diazafluoren-9-one ligands: how slight structural modification alters fluorescence mechanism

“…Zinc( ii ) and cadmium( ii ) complexes establish one of the most important classes of emissive compounds. 71–121 Earlier, we synthesized a series of mononuclear zinc( ii ) and cadmium( ii ) complexes with hybrid ligands containing a 2,2′-bipyridine moiety and natural terpene (+)-limonene or (+)-3-carene moieties and demonstrated that they exhibit luminescence with the quantum yield increasing in the following order: free ligand < cadmium( ii ) complex < zinc( ii ) complex. 122 The complexes with the limonene derivative demonstrate excitation wavelength–dependent emission with nanosecond and microsecond lifetimes of the excited states.…”
