proposed that the ''turn-on'' fluorogenic probe for Al 3+ can be constructed by ESIPT and AIEE mechanisms. Murugesapandian et al. synthesized an all-in-one type ESIPT-active multi-stimuli responsive fluorescence probe with AIE feature. Intriguingly, a kind of novel keto-salicylaldehyde azines as building blocks of AIEgens were synthesized recently by Tang et al. Yoon et al. and Zhou et al. designed the ESIPT and AIE fluorogenic probes for biothiols based on salicylaldazine dyes. To date, numerous ESIPT-active Schiffbase fluorogenic probes were developed for Al 3+ detection. Nevertheless, among them, only a few can consistently maintain the ESIPT feature, and the design strategies are still very scarce. Therefore, it is still urgently demanded novel fluorogenic probes with continuous ESIPT characteristic for Al 3+ ions and other targets estimation overcoming these limitations.
