“…There are a number of instrumental techniques [ 47 , 48 , 49 , 50 , 51 ] available for its analysis; however, there are not many options for its simple chemosensor-based detection. For a few years, rhodamine, Schiff base and naphthalimide derivative-based chemiluminescent sensor molecules have been primarily used [ 35 , 52 , 53 , 54 ]. We note here, that to the best of our knowledge, no bismuth-selective macrocyclic host molecule has yet been reported.…”

Acridino-diaza-20-crown-6 ether derivatives as new turn-on type fluorescent chemosensors with an excellent functionality and photophysical properties have been designed and synthesized for metal ion-selective optochemical sensing applications. Spectroscopic studies revealed that in an acetonitrile-based semi-aqueous medium, the sensor molecules exhibited a remarkable fluorescence enhancement with high sensitivity only toward Zn2+, Al3+ and Bi3+, among 23 different metal ions. Studies on complexation showed a great coordinating ability of logK > 4.7 with a 1:1 complex stoichiometry in each case. The detection limits were found to be from 59 nM to micromoles. The new ionophores enabled an optical response without being affected either by the pH in the range of 5.5–7.5, or the presence of various anions or competing metal ions. Varying the N-substituents of the new host-backbone provides diverse opportunities in both immobilization and practical applications without influencing the molecular recognition abilities.

“…23 Additionally, the photo-induced electron transfer (PET) results in off−on fluorescence in N-hydroxy-1,8-naphthalimide. 24 In the absence of metal ions, the fluorescence emission of N-hydroxy-1,8naphthalimide is quenched by the transfer of electrons from the lone pair of nitrogen to naphthalimide. 24 The strong coordination of Bi(III) with naphthalimide blocks the PET effect, and the turn-on fluorescence is regenerated.…”

“…Although very few fluorescent probes, such as rhodamine B/ pyrene, metal–organic frameworks, N -hydroxy-1,8-naphthalimide, and α-hydroxycarboxylic acids, have been reported for sensitive detection of Bi(III), the high-performance Bi(III) sensing using purely aliphatic intrinsically fluorescent multifunctional terpolymers suitable for diverse applications has not been reported to date. The −C O NH– and  N  functionalities of the fluorescent rhodamine B/pyrene form coordinate bonds with Bi(III).…”

Intrinsically fluorescent biocompatible multifunctional multipurpose terpolymers, i.e., methyl methacrylate-co-methyl 3-(N-isopropylacrylamido)-2-methylpropanoate-co-N-isopropylacrylamide (MMA-co-MNIPAMP-co-NIPAm, 1) and methyl methacrylate-co-methyl 3-(N-hydroxymethylacrylamido)-2-methylpropanoate-co-N-hydroxymethylacrylamide (MMA-co-MNHMAMP-co-NHMAm, 2), were synthesized via in situ-attached acrylamido-ester monomers during polymerization of hydrophobic monomers in water medium. These nonconjugated fluorescent terpolymers presenting aggregation-enhanced emissions (AEEs) were suitable for Bi(III) sensors, Bi(III) removal, cell imaging, and security inks. The fluorescence properties, mechanisms of quenching, interactions of Bi(III) with 1 and 2, and Bi(III) adsorption were explored using theoretical analyses of 1, 2, Bi(III)-1, and Bi(III)-2. Considering the overall properties, 1 was more suitable for diverse prospective applications.
