of near‐infrared (NIR)‐emissive SSBs owing to the difficulty of postmodification.

Future research on how to promote the molecular stability of SSB probes and materials during their development will remain the key point to improving their application limitations. The recent advances and extensive applications of nanotechnology have provided effective solutions for the stabilization and functional modification of SSB fluorophores in practical applications. Meanwhile, the encapsulation of SSBs into NPs can also significantly improve their biocompatibility. In the application of optoelectronic materials, the shortage of SSB's low quantum yields can be compensated by doping with high‐strength conventional fluorescent materials such as perovskites. In future research, by leveraging ESIPT and its advantages in metal ion detection, the development of SSB bioprobes and solid‐state luminescent materials with high sensitivity, full‐spectrum emission, high stability, and low biotoxicity will continue to be challenging, exciting, and of significant importance.
