“…Besides, Ln 3+ ions display weak fluorescence due to the spin- and parity-forbidden f – f transitions. 10 Developing a new detection sensor to identify a single lanthanide ion from a mixed system might solve this problem. However, few Ln–CPs have been applied to sensing Ln 3+ ions.…”

“…Lanthanide ions exhibit specific luminescence properties, including high quantum efficiency, extraordinary color purity, a long lifetime, sharp emission peaks, and large Stokes shifts [ 18 , 19 , 20 ]. Due to these merits, lanthanide luminescent materials have been widely studied in chemical and biological sensing systems [ 21 , 22 , 23 ].…”

The presence of nitrite (NO2−) in water and food leads to serious problems in public health and the environment. Therefore, it is important to develop a rapid and efficient method for the selective detection of NO2−. In this work, the synthesis and characterization of magnetic Fe3O4@SiO2-TbDPA nanoprobe have been carried out. The Fe3O4@SiO2-TbDPA aqueous solution exhibits a strong green emission. Due to the addition of various concentrations of NO2− (0–100 μM), the fluorescence intensity has been suppressed. The nanoprobe Fe3O4@SiO2-TbDPA exhibits excellent selectivity and sensitivity toward NO2− ions. Excellent linearity is obtained in the range of 5–80 μM with a detection limit of 1.03 μM. Furthermore, the presence of magnetic Fe3O4 nanoparticles in Fe3O4@SiO2-TbDPA nanospheres will also facilitate the effective separation of Fe3O4@SiO2-TbDPA from the aqueous solution. Our proposed strategy is expected to fabricate an organic-inorganic hybrid magnetic nanomaterial and can be used as an efficient sensor. It has been shown that this new strategy has numerous advantages, such as high stability, selectivity, and simplicity of operation. It demonstrates great potential for simple and convenient NO2− detection. It may expand to a variety of ranges in environmental monitoring and biomedical fields.

“…[18][19][20][21] Therefore, it is essential to design a new type of lanthanides luminescent material by the principle of "antenna effect". [22] To date, fluorescence imaging has been become an established means for real-time monitoring of living organisms. [23][24][25] Fluorescent probe, an essential tool for biological imaging, has the advantages of convenient operation, sensitive response, less biological loss, and real-time monitoring.…”

Hyperbranched polymers, as a unique highly branched polymers with low viscosity, simple synthesis, mixability and high reactivity, have received intensive attention and applied to many fields of resin modification, catalysts, and film materials. In this paper, hyperbranched polymers (P1 and P2) are designed and developed by the thiol-yne "click" reaction with controlled molar ratio of reactant. After that, lanthanide ions are coordinated with P1 and P2 to prepare new hyperbranched polymer fluorescent products (P1-Ln 3+ and P2-Ln 3+ ). P1-Ln 3+ and P2-Ln 3+ exhibit excellent fluorescent properties, superb stability, and economic feasibility. Moreover, bioimaging experiments clearly exhibit that P1-Ln 3+ and P2-Ln 3+ has great potential in further biological applications.
