“…For comparison, relevant research data for TNT detection in solution were summarized in Table 1, this calculated K sv value for TNT was comparable to those reported in the literature. [9,[14][15][16][17][18] The LOD value was obtained by monitoring the fluorescence quenching after gradually adding low concentration TNT analyte (0-3 μM). The change in fluorescence intensity was plotted against analyte concentration (Figure S6) and the LOD was calculated using the equation…”

“…Compared with documented sensors in the literature, CPPyV had comparable fluorescence quenching coefficient and lower detection limit for TNT. [9,[14][15][16][17][18] However, most sensors documented in the literature can only used in organic or mixed aqueous media, while CPPyV was purposely designed for detection of TNT in aqueous media, which was more suitable for far-ranging applications.…”

Trace detection of nitroaromatic explosives in aqueous solution is important for environmental pollution evaluation and terrorist prevention. Here, a new pyrenyl‐based aggregation‐induced emission (AIE) fluorochrome (CPPyV) with desirable fluorescent performance was synthesized and applied to detect 2,4,6‐trinitrotoluene (TNT) in water. The fluorescence of CPPyV can be selectivity and efficiently quenched by TNT. The Stern‐Volmer constant (KSV) of CPPyV for TNT was determined to be 6.2×105 M−1, with a low detection limit of 4 nM. Notably, CPPyV could be used for TNT determinations in real water samples and also developed as a fluorescent paper sensor which could efficiently detect TNT by naked‐eye when the TNT concentration was 1.0×10−8 M. The quenching process was dynamic quenching mechanism and the theoretical calculations revealed that photoin‐duced electron transfer (PET) from excited CPPyV to electron deficient TNT was the main reason for fluorescence quenching. The excellent detection performance of CPPyV yielded it a promising sensor material for actual field applications.

This comprehensive review aims to provide an in‐depth analysis of the catalytic performance of 1,5,7‐triazabicyclo[4,4,0]dec‐5‐ene (TBD) in polymer synthesis. TBD, a well‐established organic superbase, possesses a distinctive bifunctional character that grants it exceptional capabilities, particularly in processes such as transesterification or transamidation. TBD has garnered considerable attention since its initial report by Hedrick and Waymouth in 2006, and it has played a pivotal role in diverse polymerization reactions. Its versatility spans various polymerization modes, including chain‐growth and step‐growth polymerization, post‐polymerization modification, and network thermoset formation. More recently, its utility has extended to the green chemical recycling of polymers. By providing an encompassing overview of TBD's historical journey, this review delves into its past accomplishments while shedding light on its present and future potential to organocatalysts in polymer science.

Sensors are excellent options owing to their ability to figure out a large number of problems and challenges in several areas, including homeland security, defense, medicine, pharmacology, industry, environment, agriculture, food safety, and so on. Plasmonic sensors are used as detection devices that have important properties, such as rapid recognition, real-time analysis, no need labels, sensitive and selective sensing, portability, and, more importantly, simplicity in identifying target analytes. This review summarizes the state-of-art molecular recognition of biological and chemical threat agents. For this purpose, the principle of the plasmonic sensor is briefly explained and then the use of plasmonic sensors in the monitoring of a broad range of biological and chemical threat agents is extensively discussed with different types of threats according to the latest literature. A conclusion and future perspectives are added at the end of the review.
