“…Consequently, the emission intensity would be greatly increased. Thus, we expect the fluorescence to be strong in acidic media . To the best of our knowledge, these are the first successful cases of chemosensors constructed from an integration of these three specific components.…”

Two isomeric proton–receptor fluorescent probes 1 and 2 were designed and synthesised by employing the photoinduced electron transfer (PET) principle of a ‘fluorophore–spacer–receptor’ module. Their photophysical characteristics were investigated in organic solvents and Britton–Robinson buffer/EtOH (1:1, v/v) solution. Probe 1 was sensitive in the stronger acidic region of 2.21–4.56, while probe 2 displayed a good response towards protons within the pH scope of 4.10–6.09. The specificity of the probes toward protons in commonly used buffer solutions and in the presence of metal cations, Na(i), K(i), Ca(ii), Mg(ii), Al(iii), Pb(ii), Fe(iii), Ni(ii), Zn(ii), Cu(ii), Hg(ii), Ag(i), Co(ii), Cr(iii), Mn(ii), and Cd(ii) ions, was studied by monitoring the changes in their fluorescence intensity. The tested metal ions exerted no noticeable influence. The results obtained show that the synthesised proton–receptor fluorescent probes have the capability to act as pH‐sensitive probes for monitoring pH variations in the range 2.21–6.09.

“…It has the characteristics of high fluorescence quantum yield, large Stokes shift, stable optical performance, and good biocompatibility [ 52 , 53 , 54 , 55 , 56 , 57 ]. Applications in the field of biological fluorescent probes include pH probes [ 58 , 59 , 60 ], ionic probes [ 61 , 62 , 63 , 64 ], viscosity probes [ 65 ], small molecules and macromolecular [ 66 , 67 , 68 , 69 , 70 , 71 , 72 , 73 ] probes, and so on. In recent years, the use of fluorescent probes based on 1,8-naphthimide derivatives to detect hypochlorous acid in biological systems has attracted more and more attention from researchers.…”

Hypochlorous acid (HOCl) generates from the reaction between hydrogen peroxide and chloride ions via myeloperoxidase (MPO)-mediated in vivo. As very important reactive oxygen species (ROS), hypochlorous acid (HOCl)/hypochlorite (OCl−) play a crucial role in a variety of physiological and pathological processes. However, excessive or misplaced production of HOCl/OCl− can cause variety of tissue damage and human diseases. Therefore, rapid, sensitive, and selective detection of OCl− is very important. In recent years, the fluorescent probe method for detecting hypochlorous acid has been developed rapidly due to its simple operation, low toxicity, high sensitivity, and high selectivity. In this review, the progress of recently discovered fluorescent probes for the detection of hypochlorous acid was summarized with the aim to provide useful information for further design of better fluorescent probes.
