A new Cu2+-selective fluorescent probe with six-membered spirocyclic hydrazide and its application in cell imaging

Tetraphenylpyrazine-Based Manganese Metal–Organic Framework as a Multifunctional Sensor for Cu2+, Cr3+, MnO4–, and 2,4,6-Trinitrophenol and the Construction of a Molecular Logical Gate

“…Moreover, the limits of detection (LODs) for Cu 2+ and Cr 3+ are calculated to be 0.11 and 0.01 μM, respectively, according to the 3σ/ k method in the literature (Figures S13 and S14). , Besides, TippMn exhibits a rapid response for both Cu 2+ and Cr 3+ detection with a response time of less than 5 min (Figures S15 and S16). The recyclable experiments of TippMn for sensing Cu 2+ /Cr 3+ demonstrate that the sensor can be utilized for at least five cycles.…”

A salicylaldehyde benzoyl hydrazone based near-infrared probe for copper(ii) and its bioimaging applications

“…[22][23][24][25][26] To date, various NIR uorescence probes with different recognition mechanisms have been designed and used for Cu 2+ detection. [27][28][29][30] One of the most important approaches to design NIR uorescent probes for copper ion detection is to gra a Cu 2+ selective receptor unit to the uorophore. 31,32 For example, Li et al developed a NIR uorescence probe bearing 2-(1H-benzo[d]imidazol-2-yl)-phenol as a copper ion receptor.…”

Investigation of the Fluorescence Turn-off Mechanism, Genome, Molecular Docking In Silico and In Vitro Studies of 2-Acetyl-3H-benzo[f]chromen-3-one

“…The selection of quencher for the respective fluorophore mainly depends on the suitability of the molecular electronic structure of the quencher with the fluorophore. , Recently, there has been an increased interest in photochemistry and photobiology among scientists and researchers because of the potential applications of fluorescence quenching in the field of molecular dynamics and molecular imaging. The fluorescence quenching study helps in understanding the dynamic changes of proteins in complex macromolecular systems to navigate microbial cell growth, etc . − The main reason for fluorescence quenching is various molecular interactions such as energy relocation, molecular reorganization, collisional quenching, and ground-state complex formation . However, quenching mechanisms are also affected by the type of the quencher and the nature of the fluorophores .…”
