Schiff Base Aggregation-Induced Emission Luminogens for Sensing Applications: A Review

ACS Sensors, Год журнала: 2022, Номер 7(9), С. 2521 - 2536

Опубликована: Сен. 1, 2022

Fluorescence sensing can not only identify a target substrate qualitatively but also achieve the purpose of quantitative detection through change fluorescence signal. It has advantages immense sensitivity, rapid response, and excellent selectivity. The proposed aggregation-induced emission (AIE) concept solves problem traditional fluorescent molecules becoming weak or quenched in high concentration aggregated state conditions. Schiff base probes have simple synthesis, low toxicity, easy design. They are often used for various substances. In this review we cover late developments compounds with AIE characteristics working as sensors.

Simple Fluorescence Sensing Approach for Selective Detection of Fe³⁺ Ions: Live-Cell Imaging and Logic Gate Functioning

ACS Omega, Год журнала: 2022, Номер 7(37), С. 33248 - 33257

Опубликована: Сен. 12, 2022

A pyrene-based fluorescent chemosensor APSB [N-(pyrene-1-ylmethylene) anthracen-2-amine] was designed and developed by a simple condensation reaction between pyrene carboxaldehyde 2-aminoanthracene. The sensor selectively binds Fe3+ in the presence of other metal ions. Apart from this, shows high selectivity sensitivity toward ion detection. detection limit for 1.95 nM, binding constant (Kb) obtained as 8.20 × 105 M-1 DMSO/water (95/5, v/v) medium. fluorescence quantum yields APSB-Fe3+ were calculated 0.035 0.573, respectively. function this can be explained through photo-induced electron transfer mechanism which further proved density functional theory studies. Finally, live-cell image study HeLa cells also carried out to investigate cell permeability its efficiency selective living cells.

Biothiols such as cysteine, homocysteine, and glutathione play significant roles in important biological activities, their abnormal concentrations have been found to be closely associated with certain diseases, making detection a critical task. To this end, fluorescent probes become increasingly popular due numerous advantages, including easy handling, desirable spatiotemporal resolution, high sensitivity, fast response, favorable biocompatibility. As result, intensive research has conducted create for the imaging of biothiols. This brief review summarizes recent advances field biothiol-responsive probes, an emphasis on rational probe design, reaction mechanism, discriminating detection, reversible specific detection. Furthermore, challenges prospects fluorescence biothiols are also outlined.
