“…The polymer was found to emit a blue color in both solid and solution states and was expected to be used as a Zn(II) fluorescent sensor. In 2021, Zeng et al [ 39 ] synthesized a coumarin@GDP-Tb dual-emission fluorescent polymer by introducing coumarin-like luminescent groups. These coumarin@GDP-Tb polymers were then found to not only be rich in metal-binding sites but also to have moderate ion-binding power, which made them suitable as fluorescent probes that could be used for S 2− detection.…”

Aniline compounds, as a class of widely used but highly toxic chemical raw materials, are increasingly being released and accumulated in the environment, posing serious threats to environmental safety and human health. Therefore, developing detection methods for aniline compounds is of particular significance. Herein, we synthesized the fluorescent third monomer cyano-stilbene epoxide M and ternary copolymerized it with carbon dioxide (CO2) and propylene oxide (PO) to synthesize carbon dioxide-based polycarbonate (PPCM) with fluorescence recognition functions, as well as excellent performance, for the first time. The results revealed that the PPCM fluorescent probe exhibited typical aggregation-induced luminescence properties and could be quenched by aniline compounds. The probe presented anti-interference-specific selectivity for aniline compounds, and the detection limit was 1.69 × 10−4 M. Moreover, it was found to be a highly sensitive aniline detection probe. At the same time, the aniline biomarker p-aminophenol in urine could also be detected, which could expand the potential applications of polymers in the fluorescence-sensing field.

“…Ratiometric detection can be achieved through various mechanisms. (1) Luminescent ligands can function as internal references, maintaining their luminescence intensity significantly consistent before and after the introduction of the target analyte [54,55,65,67]. (2) Luminescent ligands display diminished fluorescence when coordinated within nanoparticles.…”

“…This method allows for quantitative analysis through the ratio of signals emitted at two different wavelengths, gaining significant attention as an analytical strategy due to its ability to eliminate factors such as uneven probe dispersion and variations in excitation light [43][44][45][46][47][48][49][50][51]. These additional luminescent ligands mainly consist of organic small molecules (e.g., coumarins [52][53][54], luminol [55][56][57][58][59][60], tetraphenylethene [32,61], thioflavin T [62], and 2-aminoterephthalic acid [63]) and quantum dots (e.g., carbon quantum dots [64][65][66][67][68], MoS 2 [69]). Ratiometric detection can be achieved through various mechanisms.…”

Ciprofloxacin (CIP) is a widely used broad‐spectrum antibiotic and has been associated with various side effects, making its accurate detection crucial for patient safety, drug quality compliance, and environmental and food safety. This study presents the development of a ternary nucleotide–lanthanide coordination nanoprobe, GMP‐Tb‐BDC (GMP: guanosine 5′‐monophosphate, BDC: 2‐amino‐1,4‐benzenedicarboxylic acid), for the sensitive and ratiometric detection of CIP. The GMP‐Tb‐BDC nanoprobe was constructed by incorporating the blue‐emissive ligand BDC into the Tb/GMP coordination polymers. Upon the addition of CIP, the fluorescence of terbium ion (Tb3+) was significantly enhanced due to the coordination and fluorescence sensitization properties of CIP, while the emission of the BDC ligand remained unchanged. The nanoprobe demonstrated good linearity in the concentration range of 0–10 μM CIP. By leveraging mobile phone software to analyze the color signals, rapid on‐site analysis of CIP was achieved. Furthermore, the nanoprobe exhibited accurate analysis of CIP in actual drug and milk samples. This study showcases the potential of the GMP‐Tb‐BDC nanoprobe for practical applications in CIP detection.
