“…The coordination environment of Eu(III) ions contains carboxylate oxygen atoms from the biphenyl-4,4′-dicarboxylate ligands and nitrogen atoms from 1,10-phenanthroline molecules. Such mode of metal centers binding was also observed in the other ligand mixed complexes of lanthanide ions [21,22]. For the preparation of hybrid materials containing terbium(III) ions, the complex of Tb(III) with pyridine-3,5-dicarboxylic acid (H 2 pdc) of the formula Tb 2 (pdc) 3 (DMF) 3 was used [23].…”

The synthesis and characterization of luminescent hybrid composites based on bisphenol A glycerolate (1 glycerol/phenol) diacrylate (BPA-Acr) as a cross-linking monomer and N-vinylpyrrolidone (NVP) as an active diluent, in the presence of UV initiator (Irgacure 651), are presented. Eu(III) and Tb(III) carboxylate complexes were added as luminescent components of composites. In their preparation, a constant concentration of the initiator (1%) and the BPA-Acr to NVP (10:3) ratio were applied. The structures of the obtained materials were confirmed by the infrared spectra (ATR-FTIR). Thermal properties of the cross-linked products were determined by different thermal analysis methods in air and nitrogen (TG-DTG-DSC and TG-FTIR). Thermal stability, pathways of thermal decomposition and volatile products of degradation were determined. Photoluminescence properties of the lanthanide complexes and the obtained composites were established. These materials can have the potential application as coatings filtering harmful UV radiation.

2085wileyonlinelibrary.com found to be effective in light harvesting and sensitizing the lanthanide emission through the "antenna effect." [1][2][3] Bright luminescence can be detected even if the LLCs are diluted into extremely low concentration. Therefore, LLCs are very promising for a wide range of applications, such as bioimaging, [ 4 ] immunoassay, [ 5 ] sensors, [ 6 ] light conversion fi lms for photovoltaic devices, [ 7,8 ] light emitting diode (LED) phosphors, [ 9 ] and organic LEDs (OLEDs). [ 2,10 ] Large quantities of LLCs have been synthesized and tremendous progress has been made to improve their luminescent properties. From the standpoint of materials engineering, convenient synthesis, high emission quantum yield (>0.5), and excellent photostability (no degradation >20 h under UV/blue excitation) are quite essential for successful application of such materials. [ 11 ] Up to now, photoinstability has become the major obstacle that limits the applicability of LLCs. In most conditions, lanthanide complexes (e.g., Eu 3+ and Tb 3+ chelates) harvest excitation energy from UV/blue light. However, organic ligands in the compounds are likely to be destroyed by the high energy photons. This photodegradation process has been observed in various kinds of, most currently known, lanthanide complexes. [12][13][14][15][16][17][18][19] Taking the most commonly used β-diketone derivatives as an example, although ligands like 2-thenoyltrifl uoroacetonate (TTA) and 1,3-diphenylpropane-1,3-dionate (DBM) are widely utilized for complexation of Eu 3+ ion and constructing luminescent material with high photoluminescence quantum yield (PLQY), [ 20,21 ] LLCs based on such kind of ligands suffer from serious photodegradation upon UV exposure, showing continuous decrease of the emission intensity. [ 22,23 ] To overcome this shortcoming, lanthanide complexes have been incorporated into polymers, [ 24,25 ] ionic liquids, [ 12 ] organic-inorganic hybrid systems, [ 13,19,[26][27][28][29][30][31] and so on, where the matrix plays the role of a protective cage for the complexes, strongly decreasing the UV degradation rate. However, such techniques always demand complicated synthesis process and may cause decreased PLQYs, [ 32 ] and these roles are still uncertain to remain effective for long enough time toward practical Antiphotobleaching is a critical challenge in the fi eld of luminescent lanthanide complexes (LLCs) as well as in many disciplines concerning organic luminescent processes. In this work, a type of structurally rigid organic ligand, 4-hydroxy-1,5-naphthyridine (ND), is developed, which can not only effi ciently sensitize the europium emission but also demonstrate unique photostability. A series of ND derivatives with different substituent groups are synthesized and their singlet and triplet excited state energy levels are systematically investigated. Photophysical characterizations of the corresponding europium complexes reveal that the sensitization effi ciencies ( η sens ) are close to 100% and the total photolumines...
