A Specific Fluorescent Probe for Antimony Based on Aggregation Induced Emission

Abstract

In order to find a simple way to detect Sb III in wastewater, TPE-2IPH, a fluorogen with high physical and chemical stability was simply designed and prepared by the classical one-step Schiff base reaction. The aggregation induced emission (AIE) property of TPE-2IPH was tested in the mixture of THF and water as well as its fluorescent response to antimony. It could be found that TPE-2IPH presented typical AIE property and its emission was greatly boosted with the

A Coumarin‐boronic Based Fluorescent “ON‐OFF” Probe for Hg2+ in Aqueous Solution

“…In addition, most reported bioprobes for Hg 2+ with low LOD were based on rhodamine, [ 7,21 ] some of which were time‐consuming and cost‐ineffective, while probe 1 could be easily obtained via a Schiff base reaction. [ 22 ]…”

A Pyrene‐based Probe for Antimony with Special Excimer Fluorescence

“…As reported in our previous work and other references, functional groups with N/O atoms can coordinate with antimony specifically and have been used in the design of antimony probes frequently , , . In this work, a simple N/O containing molecule, 2‐aminophenol, is linked to the pyrene core by the mild Schiff base reaction to prepare antimony chem‐sensor, Py‐IPH.…”

“…For example, Mahmoud's and Yu's groups prepared nanowires with core‐shell structure and quantum dots composed of bovine serum albumin (BSA)/CdTe for the detection of antimony, respectively, but the preparation for the materials were a little difficult , . In our previous work, a simple chem‐sensor for antimony, TPE‐IPH, was designed based on aggregation induced emission, but its fluorescent response to antimony was not high enough, which should be improved by the exploration of other kind of fluorogens based on different mechanism.…”

Aggregation Induced Emissive Luminogens for Sensing of Toxic Elements

“…In order to detect the Sb 3+ recently in 2020 Huang and group developed a new TPE‐2IPH AIE active Fluorogen with high physical and chemical stability for detection of Sb 3+ (Figure 29 ). [82] The probe TPE‐2IPH was further studied for specificity and selectivity towards different ions. However, the probe was highly selective and sensitive towards Sb 3+ shows the excellent AIE activity in THF/water fraction (Figure 30 ).…”
