Abstract
Salicylaldehyde, an essential chemical intermediate, is extensively utilized in pharmaceutical and fragrance industries. However, the excessive usage leads to environmental pollution and poses potential risks to human body. Hence, it is urgent to develop the effective sensor for the detection of salicylaldehyde (SAL). Herein, a new terbium(III)-based coordination polymer (HNU-90-Tb) is constructed by the assembly of 4-carboxytriphenylamine (HL) with Tb3+. Benefiting from the hydrophobic structure of HL, HNU-90-Tb exhibits remarkable stability in aqueous environments and is capable of maintaining structural integrity in pH range of 2-11. Notably, HNU-90-Tb enables quantitative detection of SAL through fluorescence quenching, achieving a low detection limit of 0.07 ppm and a rapid response time of just 30 s. HNU-90-Tb also shows excellent selectivity toward a variety of aldehyde analogs. The detection mechanism can be attributed to the combined inner filter effect and dynamic quenching mechanism.
期刊介绍：
ChemPlusChem is a peer-reviewed, general chemistry journal that brings readers the very best in multidisciplinary research centering on chemistry. It is published on behalf of Chemistry Europe, an association of 16 European chemical societies.
Fully comprehensive in its scope, ChemPlusChem publishes articles covering new results from at least two different aspects (subfields) of chemistry or one of chemistry and one of another scientific discipline (one chemistry topic plus another one, hence the title ChemPlusChem). All suitable submissions undergo balanced peer review by experts in the field to ensure the highest quality, originality, relevance, significance, and validity.
