“…SI 17 ). Rhodamine derivatives are also acts as photoactivatable photochromic systems under certain light conditions after being complexed with certain metal ions 57 , 58 . In this system, we did not observe any color change after addition of metal ions to the solutions of 4 and P under day light conditions for few days except for Al 3+ ion.…”

There a few reports of rhodamine-based fluorescent sensors for selective detection of only Al3+, due to the challenge of identifying a suitable ligand for binding Al3+ ion. The use of fluorophore moieties appended to a polymer backbone for sensing applications is far from mature. Here, we report a new fluorescent probe/monomer 4 and its ROMP derived polymer P for specific detection of Al3+ ions. Both monomer 4 and its polymer P exhibit high selectivity toward only Al3+ with no interference from other metal ions, having a limit detection of 0.5 and 2.1 µM, respectively. The reversible recognition of monomer 4 and P for Al3+ was also proved in presence of Na2EDTA by both UV–Vis and fluorometric titration. The experimental data indicates the behavior of 4 and P toward Al3+ is pH independent in medium conditions. In addition, the switch-on luminescence response of 4 at acidic pH (0 < 5.0), allowed us to specifically stain lysosomes (pH ~ 4.5–5.0) in live cells.

“…Later, in 2020, Li et al designed various logic gates (Figure 32) exploiting tunable optical properties of their developed material (Figure 21) in the presence of different metal ions. 66 Recently, Prof. Chowdhury and his research group developed a smart molecular logic gate 49 using the excellent reversible photochromic property of their synthesized material (Figure 22). Parts A and B of Figure 33 represent molecular logical operation and the corresponding truth table, respectively.…”

“…Within a year, in 2020, Li and coinvestigators from the College of Chemistry and Molecular Engineering, Zhengzhou University, China, developed new materials based on metal-controlled UV-light-directed photochromic behavior (Figure ). They tuned the photochromic properties by changing the various metal ions such as Zn 2+ , Ni 2+ , and Hg 2+ . The optimum metal versus L (Schiff-base ligand) mole ratios were 1:1, 1:1, and 1:2 for Zn(II), Ni(II), and Hg(II), respectively.…”

“…The photochromic phenomenon observed (2013–2022) involves mainly the excited-state intramolecular proton transfer (ESIPT). In the 1950s, Weller first proposed the ESIPT, − which involves photoinduced tautomerism. − ,,− ESIPT may be considered as a four-level photophysical process, as shown in Figure . The presence of suitable metal ions (e.g., Zn 2+ ) is essential to display the ESIPT.…”

Chromic (stimuli-responsive reversible color change in the visible region) materials have been used in a number of commercial outlets with increasing demands. It is an important scientific issue and research hot spot in recent years simply due to its huge prospects. It includes the following: (i) photochromics in sunglasses, probes, optical data storage, molecular logic-gate and keypad lock, photopatterning, and photoprinting; (ii) thermochromics in paints, inks, architecture, molecular thermometers, and cotton fabrics; (iii) mechnochromics in plastics, textiles, and anticounterfeiting systems; (iv) electrochromics in switchable glass, smart paper strips, and flexible electronics; (v) halochromics in digital image colorimetry and acid−base indicators; (vi) ionochromics in colorimetric sensors and complexometric indicators; and (vii) hydrochromics in water-jet printing. The well-known rhodamine B (RhB) dye has now been considered a unique stimuli-dependent chromic material by researchers because of its outstanding photophysical and physicochemical properties that are suitable for real applications. In this review work, almost all of the works published on RhB-based stimuli-responsive materials from 1977 to 2022 have been studied critically, and significant progress is arranged in chronological order. In addition, an attempt has been made to show the prospects of what they can do in human service in the near future.

“…From 2014 to 2020, the Rhodamine B salicylaldehyde hydrazone metal complex appeared as a new photochromic system that could be used both in solution and in a solid matrix with good fatigue resistance. 9,[17][18][19] Interestingly, it has been observed that a proton transfer between the phenolic-OH group of the salicylaldehyde part and imine N of the hydrazone part, i.e., keto-enol tautomerism, plays an important role in the photochromic property of the metal-ligand coordination complexes. However, the mechanistic pathway (the passage of the proton transfer, transition states involved) by which the photochromic process proceeds remained unclear for several years.…”
