A new single-armed salamo-based sensor with aggregation-induced emission characteristic for selective sensing of aluminium ions

Coordination-Driven Salamo-Salen-Salamo-Type Multinuclear Transition Metal(II) Complexes: Synthesis, Structure, Luminescence, Transformation of Configuration, and Nuclearity Induced by the Acetylacetone Anion

“…The absorption intensity at each peak position did not change when Ni­(OAc) 2 reached 4.0 eq, which indicates that the optimal ratio of the ligand H 4 L to Ni 2+ is 1:4. In addition, the linear graph based on the change in the absorption intensity and the Ni 2+ concentration showed that the absorption intensity of H 4 L has a good linear relationship with Ni 2+ . , …”

“…In addition, the linear graph based on the change in the absorption intensity and the Ni 2+ concentration showed that the absorption intensity of H 4 L has a good linear relationship with Ni 2+ . 63,64 In addition, the excited-state properties and electronic structures of complexes 1−4 are illustrated in Figures 17 and S10−S12. In the case of complex 1, the band at 298.87 nm arises from the π → π* and n → π* transitions due to H + 15 to L + 34 excitation (S 0 → S 149 , 12.72%), the absorption at 312.25 nm predominantly contributed by the transition from the H + 18 to L + 20 excitation (S 0 → S 136 , 11.29%), the band at 341.89 nm arises from the π → π* and n → π* transitions due to H + 10 to L + 25 excitation (S 0 → S 116 , 5.93%), the band at 355.20 nm arises from the π → π* and n → π* transitions due to H + 15 to L + 32 excitation (S 0 → S 105 , 4.34%), and the band at 390.42 nm is due to H + 19 to L + 36 excitation (S 0 → S 90 , 13.80%) (Figure 17).…”

A novel coumarin derivative-modified cellulose fluorescent probe for selective and sensitive detection of CN− in food samples

“…The HRMS was conducted using methodology reported in the published literature. 31,32,33 From the results in published literature and the experimental results, a mechanism was proposed for the interaction between DCB and CN − (Fig. 8).…”

A supramolecular fluorescence array sensor for toxic heavy metal ion detection in environmental water and rice seedling extracts

“…Chemical sensors, such as nanomaterials, 11 metal–organic frameworks, 12 polymers, 13 fluorescence chemosensors, 14–17 and supramolecular optical array sensors, have been widely used in the field detection of a variety of heavy metals. 18 Of interest, fluorescent probes can detect bioactive molecules such as Cys, Hcy, and GSH 19 and formaldehyde and sulfenic acids 20 in plants.…”
