“…The quantum yields of the cyclization and cyclization reactions for the determination of 1o were 0.54 and 0.02, respectively. 36 The fatigue resistance of 1o indicates that for alternating ultraviolet/visible irradiations, 1o was only reduced by 10.3% after coloring-discoloration cycles executed ten times (Fig. S3 † ).…”

“…Although, research in recent years has produced relevant advances in the development of optical HSO 4 − and AcO − chemosensors based on different strategies, such as organic compounds containing amide, amine, phenol, hydrazone, pyrrole, urea, imidazole, flavone, triazole, indole and thiourea together with positively charged subunits (imidazolium, guanidinium, pyridinium) that are capable of providing H‐bond donors to recognize anions, these available organic chemosensors have some limitations such as low hydro‐stability, low water solubility, and insufficient selectivity or sensitivity [19–56] . Another strategy is based on the design of metal complex chemosensors, since the presence of the metal ion not only provides additional binding sites for the guest anion but also structurally pre‐organizes the binding sites for optimal anion‐binding via hydrogen bonding and metal ion coordination, resulting in a strong affinity when are compared to purely organic chemosensors [57–68] .…”

New complex [RuLCl2(PPh3)] (L= N,N‐bis(2‐hydroxy‐5‐nitrobenzaldehyde)‐2,2’‐diaminodiethylamine) was prepared and characterized analytically. [RuLCl2(PPh3)] was employed as a luminescent chemosensor for the detection of anions. The results show that [RuLCl2(PPh3)] can detect HSO4 ̄ and AcO ̄ selectively with sequential order in H2O‐CH3CN (8:2, v/v) at pH 7.0. The spectral binding, titration, and interference analyses reveal that the addition of HSO4 ̄ to [RuLCl2(PPh3)] emits a distinguished fluorescence intensity (IF/I0= 6.55) significantly. This shows that HSO4 ̄ interacts suitably with the complex to switch ON the fluorescence which could be explained by inhibition of a PET mechanism as the above addition forms [RuLCl(HSO4)(PPh3)] in the excited state. Selectivity of [RuLCl2(PPh3)] with HSO4 ̄ forms [RuLCl(HSO4)(PPh3)] in the water showing a negligible change in its emission except for AcO ̄, which enhances fluorescence intensity. For the addition of AcO ̄ to [RuLCl2(PPh3)] forms [RuLCl(AcO)(PPh3)], however, the adding of HSO4 ̄ to [RuLCl(AcO)(PPh3)] does not show any change in the intensity, suggesting that there exists a logic gate function for the addition of HSO4 ̄ followed by AcO ̄ to [RuLCl2(PPh3)]. This finding is interesting because [RuLCl2(PPh3)] can act as a fast selective chemosensor for the sequential detection of HSO4 ̄ and AcO ̄.

“…Schiff bases are easily prepared binding sites (N and O atoms), which is one of the most potent characteristics. [ 56,57 ] Thus, the design of a unique sensor with high sensitivity and selectivity for zinc is great important. Based on the mentioned, we designed and synthesized a new diarylethene‐based fluorescent sensor ( 1o ) for Zn 2+ as displayed in Scheme 1.…”

A novel fluorescent sensor on the basis of diarylethene and benzohydrazide unit was successfully synthesized. Its photochromic and fluorescent switching properties have been studied in detail by the irradiation of UV‐visible (UV‐Vis) lights and the stimulus of Zn2+/EDTA. The sensor exhibited high sensitivity and selectivity toward Zn2+ in tetrahydrofuran, which is not interfered by other cations, especially of congener Cd2+. The fluorescence intensity enhanced 84 times along with a 44‐nm blue shift of the emission peak after adding Zn2+. The stoichiometric ratio between the sensor and Zn2+ was 1:1, and the limit of detection (LOD) was calculated as 5.60 × 10−9 mol L−1. Besides, the sensor was applied in the detection of practical water samples with high accuracy.
