“…Copper(II) is a common element and is crucial for the development, growth, and fitness of living organisms . However, a of deficiency Cu 2+ or excessive Cu 2+ in the living body may cause various health issues because Cu 2+ has good redox properties, which are responsible for the production of reactive oxygen species (ROS). , Therefore, researchers have been attracted to developing a selective, sensitive, cost-effective fluorescent probe for the sensing of Cu 2+ ions. There are several reports regarding the use of spiropyran based fluorescent probes for selective detection of this metal ion.…”

Due to ever-increasing insights into their fundamental properties and photochromic behaviors, spiropyran derivatives are still a target of interest for researchers. The interswitching ability of this photochrome between the spiropyran (SP) and merocyanine (MC) isoforms under external stimuli (light, cations, anions, pH etc.) with different spectral properties as well as the protonation–deprotonation of its MC form allows researchers to use it suitably in sensing purposes by developing different colorimetric and fluorometric probes. Selective and sensitive recognition can be achieved by little modification of its SP moiety and functional groups. In this review, we emphasize the recent advancements (from 2019 to 2022) of spiropyran–merocyanine based fluorogenic and chromogenic probes for selective detection of various metal ions, anions, neutral analytes, and pH. We precisely explain their design strategies, sensing mechanisms, and biological and environmental applications. This review may accelerate the improvements in designing more advanced probes with innovative applications in the near future.

“…In comparison to other organometallic compounds boron extends rigidity within the molecule and are comparatively more stable due to increase in covalency of BÀ O and BÀ N bonds. [55][56][57][58] Also, the chromo and fluorogenic properties of stable boron complexes [57][58][59][60][61][62] of Schiff's bases and azines, having NÀ BÀ N and NÀ BÀ O type core structure are analogous to BODIPY [61] and are explored for cell imaging and development of chemosensors and biosensors. Wu et al developed gelators of β-iminoenolate boron complexes to detect acid.…”

Synthesis and photophysical properties of a fluorescent probe HBD is described. Probe upon interaction with metal ions, anions and nucleoside pyrophosphates (NPPs) showed fluorescence quenching with Cu2+ due to chelation enhanced quenching effect (CHEQ). Moreover, interaction of ensemble HBD.Cu2+ with anions and NPPs showed fluorescence “turn‐On” response with ATP selectively. “On–Off–On” responses observed with Cu2+ and ATP is attributed to an interplay between ESIPT and TICT processes. Cyclic voltammogram of probe exhibited quasi‐reversible redox behaviour with three oxidation and two reduction potentials and the change in band gaps of probe suggested the interaction with Cu2+ and ATP. The 2:1 and 1:1 binding stoichiometry for an interaction between probe and Cu2+ (LOD, 62 nM) and ensemble, HBD.Cu2+ with ATP (LOD, 0.4 µM) respectively are realised by Job’s plot and HRMS data. Cell imaging studies carried out to detect Cu2+ and ATP in HeLa cells. Also, the output emission observed with Cu2+ and ATP is utilized to construct an implication (IMP) logic gate. Test paper strips showed naked‐eye visible color responses to detect Cu2+ and ATP. In real water samples probe successfully detected copper (0.03 µM) between 5‐6.5 ppb level (ICP‐MS method).
