The study presents the development and analysis of a novel Al3+ detecting compound, 4-(2-(4-hydroxy-3-((quinolin-3-ylimino)methyl)phenyl)propan-2-yl)-2-((quinolin-3-ylimino)methyl)phenol (abbreviated as H2P). The probe was obtained by a simple condensation of bisphenol A dialdehyde and 3-amino quinoline (1:2 ratio) in methanol under mild conditions. A distinct color change was observed in the bare eye under UV light in the presence of Al3+, whereas other metal ions remained unresponsive. The fluorescence probe demonstrates a remarkable enhancement in fluorescence intensity, specifically a 29-fold increase at 466 nm, when exposed to Al3+. This phenomenon has been attributed to two mechanisms: the chelation enhanced fluorescence (CHEF) effect and the inhibition of C=N isomerization. The probe exhibits high sensitivity toward Al3+, with a detection limit of 1.48 × 10−7 M. Furthermore, it forms a complex with the cation in a 1:2 ratio (ligand to metal), characterized by an association constant of 3.30 × 104 M−1.

Comprehensive characterizations demonstrated that the R-CDs were uniform spheres with an average diameter of 2.56 nm and exhibited red fluorescence at 615 nm under 555-nm excitation. The R-CDs could form non-fluorescent ground-state aggregates with Cu2+, resulting in an increase in the average particle size to 3.70 nm. The aggregation also caused a significant fluorescence quenching through a static mechanism, concomitant with a change of the R-CDs solution. Consequently, a fluorescence-colorimetric dual-mode sensor was constructed for Cu2+ detection, with a LOD of 90 nM in the fluorescence mode and 0.73 μM in the colorimetric mode.

Therefore, rapid and sensitive detection of Cys is of great significance for early disease diagnosis and mechanistic studies. In this work, we developed a novel near-infrared (NIR) fluorescent “turn-on” probe, NA-XL, featuring a large Stokes shift (177 nm) for highly efficient detection of the biothiol Cys. The probe incorporates a naphthalimide fluorophore and an acrylate group that serves as both the Cys recognition site and fluorescence quencher. The fluorescence quenching of NA-XL is predominantly governed by strong low-frequency vibrations. Upon selective reaction with Cys, this vibration-mediated quenching process is effectively suppressed, leading to a pronounced NIR fluorescence emission at 729 nm. The probe demonstrates excellent selectivity and sensitivity, achieving a low detection limit (LOD) of 10.7 nM. Furthermore, NA-XL exhibits outstanding responsiveness to both exogenous and endogenous Cys in cellular imaging, enabling real-time monitoring of Cys dynamics.
