“…30 However, the LOD calculated in this work is a value that is in the same order of magnitude compared with other chemosensors recently reported in the literature. 31−33 In order to determine the stoichiometry of the complex, the Job’s plot study of the fluorescence emission for 3b –Hg 2+ interaction was made. This curve showed a maximum around 0.3 indicating the formation of complex 3b :Hg 2+ with a molar ratio that can be between 2:1 and 3:1 (Figure 6).…”

A convenient access toward novel fluoroionophores based on 1-(2-pyridyl)-4-styrylpyrazoles (PSPs) substituted at position 3 with donor or acceptor aryl groups is reported. The synthesis proceeds in two steps: the first one via Wittig olefination of the appropriate 4-formylpyrazole and then Mizoroki–Heck coupling to yield the desired products in an overall yield of up to 69%. Photophysical properties of products (4-styryl) and their intermediates (4-vinyl) were explored, finding that they have strong blue-light emission with high quantum yields (up to 66%) due to ICT phenomena. The 3-phenyl PSP was studied as a turn-off fluorescent probe in metal ion sensing, finding a high selectivity to Hg2+ (LOD = 3.1 × 10–7 M) in a process that could be reversed with ethylenediamine. The sensing mechanism and binding mode of the ligand to Hg2+ were established by HRMS analysis and 1H NMR titration tests.

“…The interesting fact about all these ferrocene‐based ions recognition systems is that upon complexation with metal cations or hydrogen bond formation with anions, they undergo significant perturbations of the ferrocene/ferrocenium redox couple. The values of the corresponding anodic or cathodic oxidation potential shifts provide information about the strength of the recognition event …”

Individually, ferrocene and photochromic materials have several important attributes and applications. Ferrocene is a promising candidate of stimuliresponsive materials due to its electronic, electrochemical and magnetic properties. On the same lines, photo-sensitive materials are also an important class of stimuli-responsive materials which can be modified according to the needs.Recently, a lot of keen attention has been given to the combination of ferrocene with different photo-sensitive moieties to get novel functional materials. This review illustrates the research advances in the combination of ferrocene-based small molecules, self-assembled monolayers and polymers with photo-responsive compounds and their potential applications.

A novel long-wavelength turn-on fluorescent chemosensor CS based on pyrene was synthesized to detect Hg2+. In the presence of other metal ions, CS could effectively recognize Hg2+ and produce the turn-on fluorescent emission at 607 nm. Also, the absorption spectrum exhibited red-shift. Meanwhile, the change of the solution color from yellow to orange was directly observed by the naked eye. The interaction between CS and Hg2+ was confirmed by the Job’s plot, electrospray ionization mass spectrometry, scanning electron microscopy, and density functional theory calculations. It was found that the fluorescence of CS could be reversible when I– was added into the solution of CS and Hg2+. CS illustrated high selectivity and good sensitivity for Hg2+ with the limit of detection of 36 nm. Moreover, CS could be utilized as test strips and silica gel plates to identify Hg2+.
