“…In our investigation, we found that the fluorescence intensity of the complex in PP matrix gradually faded upon UV exposure. Bojinov et al once reported that tetramethyl piperidine may protect some fluorophores from photodegradation . In this work, to examine the influence of MTPS on the fluorescence stability of the resulting complexes, the intensity fading rate of PP/EuMP is compared with PP/EuLP by photoluminescence spectra.…”

A novel hindered amine ligand, mono-2,2,6,6-tetramethyl-4-piperidyl-succinate (MTPS), has been designed to chelate europium(III) ion with 1,10-phenanthroline (Phen) as a coligand to prepare polymer photostabilizer. The luminescent property of the stabilizer and its efficiency of protecting polymer matrix from photodegradation have also been investigated. Under UV excitation, the stabilizer has red light emission in both ethanol solution and polypropylene (PP) matrix. The PP sheets containing the stabilizer display significantly improved photostability, which may be attributed to MTPS which scavenges radical, as well as Phen which makes the complex dissipate the absorbed ultraviolet light in a harmless manner. These preliminary results demonstrate that the introduction of the stabilizer can endow polymer matrices not only excellent photoluminescent properties but also improved photostability.

The synthesis of a new 1,8‐naphthalimide‐based fluorescence turn‐off chemosensor for the effective detection of Cu(II) ions is reported. The chemosensor MAST was characterised by mp, Fourier Transform‐infrared (FTIR), ultraviolet‐visible (UV‐vis), fluorescence, 1H‐NMR and 13C‐NMR spectroscopy, and mass spectrometry. After treatment with Cu(II) ions in coexistence with various competitive metal ions in a dimethylsulphoxide (DMSO)/4‐(2‐hydroxyethyl)‐1‐piperazineethanesulphonic acid (HEPES) buffer solution (v/v, 1:1; pH 7.4), the chemosensor demonstrated high selectivity towards Cu(II) ions and a fluorescence quenching of 83.67% was observed. In addition, a good linear response for the chemosensor detecting Cu(II) ions was obtained over the concentration range 0.2–1 μm. The combined results of UV‐vis and fluorescence titrations with the Job plot yielded a 1:1 stoichiometric interaction of the chemosensor with Cu(II) ions. The association constant and detection limit were calculated as 1.37 x 106 m−1 and 1.69 x 10−8 m, respectively. Based on results, the quenching response of MAST towards Cu(II) ions could be ascribed to the reverse‐photoinduced electron transfer (PET) mechanism. Finally, the proposed chemosensor was applied to quantify Cu(II) ions in real‐world water samples and excellent recovery rates of 98–105.8% were obtained.
