“…High concentrations of Cu 2+ may cause gastrointestinal disturbance and damage to the liver or kidney. Accordingly, fluorescent and colorimetric sensors for the detection of Cu 2+ have received increasing scientific attention . Among common fluorophores, rhodamine derivatives are widely employed as a fluorescent dye for detection of metal ions due to their excellent photophysical properties such as long absorption and emission wavelengths, large molar extinction coefficient, high fluorescence quantum yield and great photostability .…”

A rhodamine-based fluorescent chemodosimeter rhodamine hydrazide-triazole (RHT) tethered with a triazole moiety was developed for Cu 2+ detection. In aqueous medium, the RHT probe exhibited high selectivity and sensitivity toward Cu 2+ among other metal ions. The addition of Cu 2+ triggered a fluorescence emission of RHT by 384-fold (Φ = 0.33) based on a ring-opening process and a subsequent hydrolysis reaction. Moreover, RHT also showed a selective colorimetric response toward Cu 2+ from colorless solution to pink, readily observed with the naked eye.The limit of detection of RHT for Cu 2+ was calculated to be 1 nM (0.06 ppb). RHT was successfully demonstrated to detect Cu 2+ in Chang liver cells by confocal fluorescence microscopy.

“…The pH values were suitably adjusted using dilute hydrochloric acid. Intermediate compounds N ‐allyl‐4‐bromo‐1,8‐naphthalimide, N ‐allyl‐4‐piperazinyl‐1,8‐naphthalimide, and allylpiperazine were synthesised as described previously in the literature . 4‐Bromo‐1,8‐naphthalic anhydride, iminodiacetic acid diethyl ester, and ammonia solution were obtained from commercial sources.…”

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.

“…The polymer was synthesized by photo‐copolymerisation of probe 11 with 2‐hydroxyethyl methacrylate (HEMA) on a glass treated with a silanizing agent ( Figure a). [ 81 ] The fluorescence response of the sensor toward various metal ions (Cu 2+ , Co 2+ , Ni 2+ , Zn 2+ , Fe 3+ , Cd 2+ , Ag + , Hg 2+ , and Pb 2+ ) were investigated in a buffered (Tris–HCl, pH 7.24) aqueous solution. The fluorescence studies revealed that the optode membrane shows strongest quenching in the presence of Cu 2+ ions.…”

The beginning of the 21st century was marked by the intensive development of fiber‐optic sensors. New functional materials with excellent sensory properties are required to design such sensors. Fluorescent probes for neutral and charged molecules are constantly developing. However, only a small part of the reported probes was successfully converted into functional sensing polymers and found real‐world applications. A great challenge is to retain the sensing properties of a probe in a polymer matrix. The purpose of this review is to understand how properties of a probe are changed upon incorporation into a polymer and to reveal successful approaches. The review focuses on the use of the naphthalimide‐based probes in the construction of sensing polymers. The literature overview is presented according to the nature of the guest molecules targeted for the quantitative detection: cations, anions, and small organic molecules.
