Abstract
A chitosan-based Cu2+ fluorescent probe was designed and synthesized independently using the C-2-amino group of chitosan with 1, 8-naphthalimide derivatives. A series of experiments were conducted to characterize the optical properties of the grafted probe. The fluorescence quenching effect was investigated based on the interactions between the probe and common metals. It was found that the proposed probe displayed selective interaction with Cu2+ over other metal ions and anions, reaching equilibrium within 5 min.

Abstract
In recent decades, researchers have conducted in-depth studies of the design and synthesis of colorimetric/fluorometric probes and the application of such probes to biological and practical samples. The multifunctional colorimetric and fluorescent azo benzene-based probe (4′-hydroxyl-2,4-diaminoazobenzene, MP) was designed to detect Al3+, Fe3+, Cu2+ and F¯. Based on the distinct redshift of the absorption band and a significant color change (yellow → purple), MP was utilized for both naked-eyed and quantitative detection of Al3+ and Fe3+ after formation of the 1:1 complex. Test paper coated with MP and used in conjunction with a cell phone was used for colorimetric detection of Al3+ and Fe3+ ions (20 μM–2.0 mM) in water samples through naked-eye and digital image colorimetry. The “MP-Fe3+” coordination shift that occurs in the presence of the competitive ligand F¯ was used in the colorimetric measurement of F¯ in toothpaste. In the presence of Cu2+ ion, the non-emissive MP has transformed into fluorescent benzotriazole product PMP (Φ = 0.53) through the bimolecular rate-limiting step, and the second-order rate constant k is calculated as 31 ± 2 M−1 s−1. MP exhibits a “turn-on” fluorescence response in the presence of Cu2+ that is greater than its response in the presence of competitive species such as Fe3+, Al3+, Co2+, Fe2+, Zn2+, Cd2+, Mg2+, Mn2+, Ni2+ and Ag+. MP was shown to have low toxicity to living HeLa cells and to present good imaging characteristics for tracking of Cu2+ in vivo.

Abstract
Two Schiff-base fluorescent probes (1 and 2) were directly synthesized from natural cinnamaldehyde, and they were characterized by FT-IR, 1H and 13C NMR, HRMS. Compound 1 had no fluorescence, while compound 2 could emit significant yellow fluorescence in solid and provide green light in solution. Probe 1 could selectively sense ClO- with a fluorescence enhancement, providing a good linear relationship between the fluoresence intensity and ClO- concentrations (0-5.5 × 10-5 mol/L), y = 175.64x-19.399, R2 = 0.9937, and the limit of detection (LOD) was 39.4 nM. Probe 2 was sensitive for Cu2+ by quenching with two linear relationships at the Cu2+ concentrations from 0 to 2.1 × 10-5 mol/L, LOD = 73.9 nM. Furthermore, live celluar imaging of human astrocytoma U-251 MG cells and human liver cancer cells (Hu-7) had achieved using the 1 + ClO- and 2, offering clear intracellular fluorescence. Finally, the 1 + ClO- and 2 could also be used to dye bamboo tissues for a good use. Thus, the cinnamaldehyde derivatives could be further used in the field of celluar and bamboo imaging.

Abstract
A simple, sensitive colorimetric probe for detecting Cu(ii) ions with fast response has been established with a detection limit of 2.82 μM. UV-Vis spectroscopy along with metal ion response, selectivity, stoichiometry, competition was investigated. In the presence of copper(ii), the UV-Vis spectrum data showed significant changes and the colorimetric detection showed a color change from colorless to yellow. After the selective binding of receptor L with Cu(ii), the UV-visible absorption at 355 nm decreased dramatically, a new absorbance band appeared at 398 nm and its intensity enhanced with the increase in the amount of Cu(ii). Moreover, it exhibited highly selective and sensitive recognition towards Cu(ii) ions in the presence of other cations over the pH range of 7-11. The complex structure was verified by FT-IR spectroscopy, elemental analysis and quantum mechanical calculations using B3LYP/6-31G(d) to illustrate the complex formation between L and Cu(ii). According to the Job plot and the quantum mechanical calculations, the stoichiometric ratio for the complex formation was proposed to be 1 : 1.

Abstract
In the present study, a colorimetric azobenzene-based probe (AZO 1) was reported that exhibits high selectivity toward Cu2+ and undergoes a red to yellow colour change upon its detection. Density functional theory (DFT) calculations were carried out to investigate the mechanism of the probe discoloration. The differences in the binding energies of complexes of 2 : 1 and 1 : 1 stoichiometry indicated that a two-step complexation process takes place as the Cu2+ content increases. However, the calculated absorption spectra suggested that a significant colour change would only be observed for the 1 : 1 AZO 1 : Cu2+ complex. A HOMO–LUMO electronic transition was a key factor for the blue shift of the absorption bands of the probe. Further studies indicated that solvent molecules participate in the complexation and that the presence of the o-methoxy group in AZO 1 led to formation of an octahedral complex because of the additional chelating site. A significant change in the conformation of AZO 1, namely the rotation of the N,N-di(carboxymethyl)amino group around the N–CAr bond by approximately 90°, resulted in a larger HOMO–LUMO energy gap, and the corresponding alteration of the intramolecular charge transfer (ICT) from the N,N-di(carboxymethyl)amino group to the phenyl ring led to the observed colour change. DFT calculations indicated that the rotation of the N,N-di(carboxymethyl)amino group around the N–CAr bond by approximately 90°, resulted in a larger HOMO–LUMO energy gap, and led to the observed colour change.![]()
