“…101 (3) The practical application of rapid detection of analytes is also hampered as SP derivatives are sparingly watersoluble and its ring opening needs photoinduction. 26 Moreover, the following properties should be prioritized for more precise sensing by using this platform: (1) NIR design is required because it provides deep tissue penetration strength with minimal photo damage to the sample. (2) The probe should be ratiometric in order to eliminate environmental factors, probe concentration fluctuations, and instrumental errors.…”

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.
