“…However, the addition of Hg II results in only a minimal enhancement in the emission. Recently, Park and co‐workers have described “turn‐on” fluorescence sensor 51 based on rhodamine that selectively detects Cu II ions over others metal ions such as Hg II , Co II , K I , Cs I , Ag I , Pb II , Zn II , Mg II , Fe III , Ni II , Li I , and Al III . Probe 51 shows unprecedented colorimetric (from colorless to pink) and fluorometric (from colorless to yellowish green) changes in the presence of Cu II on the basis of the ring‐opening mechanism of the rhodamine spirolactam with a 1:1 (ligand/metal) binding ratio.…”

Red and green are two of the most‐preferred colors from the entire chromatic spectrum, and red and green dyes are widely used in biochemistry, immunohistochemistry, immune‐staining, and nanochemistry applications. Selective dyes with green and red excitable chromophores can be used in biological environments, such as tissues and cells, and can be irradiated with visible light without cell damage. This critical review, covering a period of five years, provides an overview of the most‐relevant results on the use of red and green fluorescent dyes in the fields of bio‐, chemo‐ and nanoscience. The review focuses on fluorescent dyes containing chromophores such as fluorescein, rhodamine, cyanine, boron–dipyrromethene (BODIPY), 7‐nitobenz‐2‐oxa‐1,3‐diazole‐4‐yl, naphthalimide, acridine orange, perylene diimides, coumarins, rosamine, Nile red, naphthalene diimide, distyrylpyridinium, benzophosphole P‐oxide, benzoresorufins, and tetrapyrrolic macrocycles. Metal complexes and nanomaterials with these dyes are also discussed.

“…The complexation ratio of the fluorescent complex formed by the combination of sulfate ions and AMDP was researched by the Job plot method [43,44], as shown in Figure 6a. This result was confirmed by the Job plot method in which the fluorescence intensity exhibits a maximum at a molar fraction of approximately 0.5, indicating that a 1:1 stoichiometry was the most likely binding mode for AMDP and SO 4 2− ion.…”

A new optical fiber sensor based on the fluorescence lifetime was prepared for specific detection of sulfate ion concentration, where 1,1′-(anthracene-9,10-diylbis(methylene))bis(3-(dodecylcarbamoyl)pyridin-1-ium) acted as the sulfate fluorescent probe. The probe was immobilized in a porous cellulose acetate membrane to form the sensitive membrane by the immersion precipitation method, and polyethylene glycol 400 acted as a porogen. The sensing principle was proven, as a sulfate ion could form a complex with the probe through a hydrogen bond, which led to structural changes and fluorescence for the probe. The signals of the fluorescence lifetime data were collected by the lock-in amplifier and converted into the phase delay to realize the detection of sulfate ions. Based on the phase-modulated fluorometry, the relationship between the phase delay of the probe and the sulfate ion concentration was described in the range from 2 to 10 mM. The specificity and response time of this optical fiber sensor were also researched.

“…Rhodamine uorophores have excellent photophysical properties, such as large absorption extinction coefficients, sharp uorescence emissions and high uorescence quantum yields. Moreover, they can undergo great uorescence enhancements via a structural change from the spirocyclic state (non-uorescent) to the ring-open (uorescent) state, induced by metal ions, inorganic anions, [10][11][12][13] etc. Their absorption and emission spectra appear at a longer wavelength (ca.…”
