Fluorogenic probe presents the benefits of methodological simplicity, brief reaction time, high sensitivity, low LOD, cost-efficiency, accuracy, and capability of noninvasive fluorescence imaging in biological systems as compared with the conventional sensing protocols for specific metal ions. Thus far, there has been a striking progress in fluorogenic probes for the sensing of Al and other metal ions based on various sensing mechanisms. The response mechanisms utilized for fluorogenic probe design generally involve the following: AIE (aggregation-induced emission), ESIPT (excited state intramolecular proton transfer), PET (photoinduced electron transfer), ICT (intramolecular charge transfer), CHEF (chelation-enhanced fluorescence), FRET (fluorescence resonance energy transfer), CL (chemiluminescence), TBET (through bond energy transfer), and TICT (twisting intramolecular charge transfer), etc. Amongst them, ESIPT-active fluorogenic probes have gained considerable attention because they offer promising superiorities, such as large Stoke shift, strong brightness, high sensitivity and outstanding photostability. The existing researches demonstrate that the intramolecular Hbonding between H acceptor (=N-and C=O) and H donor (-OH and NH2) groups is ordinarily essential for the ESIPT molecules. The most commonly used ESIPT fluorogenic building blocks including the typical backbones of SSB (salicylaldehyde-based Schiff-base), flavones, benzophenones and HPQ (hydroxyphenylquinazolinone), and the analogues of HBT (2-(2'-hydroxyphenyl)benzothiazole), HBI (2-(2'hydroxyphenyl)benzimidazole) and HBO (2-(2'-hydroxyphenyl)benzoxazole), and so on. Generally, ESIPT is a distinctive four-level phototautomerization process (Enol-Enol * -Keto * -Keto). More specifically, in the S0 state, the molecules typically existing as an E form with the intramolecular H-bond, i.e., O─H⋅⋅⋅N, O─H⋅⋅ ⋅O, and N─H⋅⋅⋅N. Upon photoexcitation to the E* form, proton transfer takes place from H donor to H acceptor to generate the K* form with the change of intramolecular H-bond (O⋅⋅⋅H─N, O⋅⋅⋅H─O, and N⋅ ⋅⋅H─N). The K* form can decaying radiatively return to the K form and then a RPT (reverse proton transfer) occurs to produce the original E form. According to the energy barrier difference of ESIPT, single-emission from E* form or dual emission from E* form and K* form can be experimentally observed. Thanks to this extremely fast photochemical process, ESIPT molecules are featured by some particularly charming traits that make them valuable for fluorogenic probes, bioimaging agents and OLEDs, etc. In recent years, SSBderivated ESIPT fluorophores have been popularly used for designing the fluorogenic probes for ions (metal cations and anions), small molecules, biomolecules, and chemicals and others because of their easy access to synthesize and modify as well as the excellent photophysical properties.
