Special Issue Information

Dear Colleagues,

With the rapid development of industrialization, the increasingly extensive release of environmental pollutants  (antibodies, pesticides, heavy metal ions, pathogens, etc.) has become an issue that poses a severe threat to human health and ecological safety. Therefore, it is very essential to find ways to efficiently monitor and remediate environmental pollutants. In this respect, fluorescent chemical sensing has received significant research attention as a rapid,  low-cost, on-site, and versatile technique to monitor various environmental pollutants. Meanwhile, photocatalysis has emerged as a promising technique to remediate a variety of environmental contaminants by utilizing green and sustainable solar energy.

This Special Issue aims to showcase original research papers on chemical fluorescent sensors and photocatalytic materials used for the detection/remediation of environmental pollutants. These materials include organic materials, inorganic materials, polymers, hybrid materials, and so on, while the applications consist of the detection and remediation of the environmental pollutants in water, air, and soil.

To monitor the biological function of H2S in real time, this investigation demonstrated the design and synthesis of a novel fluorescent probe integrated with cyanine and 2,4-dinitrophenol for the qualitative and quantitative detection of H2S. An NIR sensitive sensor (FS-HS-1) was provided with a straightforward process. Spectroscopy experiments elucidated that FS-HS-1 could selectively detect H2S in a PBS solution (containing 40% acetonitrile) with a 111-fold fluorescence enhancement at 715 nm (ex. 605 nm). The response towards NaHS occurred in less than 2 min, and the detection limit was confirmed to be as low as 4.47 ± 0.11 nmol/L. Furthermore, the probe is capable of monitoring changes in exogenous H2S concentrations within living cells with confocal and 2P imaging. Full article

The field of fluorescence sensing, leveraging various supramolecular self-assembled architectures constructed from macrocyclic pillar[n]arenes, has seen significant advancement in recent decades. This review comprehensively discusses, for the first time, the recent innovations in the synthesis and self-assembly of pillar[n]arene-based supramolecular architectures (PSAs) containing metal coordination sites, along with their practical applications and prospects in fluorescence sensing. Integrating hydrophobic and electron-rich cavities of pillar[n]arenes into these supramolecular structures endows the entire system with self-assembly behavior and stimulus responsiveness. Employing the host–guest interaction strategy and complementary coordination forces, PSAs exhibiting both intelligent and controllable properties are successfully constructed. This provides a broad horizon for advancing fluorescence sensors capable of detecting environmental pollutants. This review aims to establish a solid foundation for the future development of fluorescence sensing applications utilizing PSAs. Additionally, current challenges and future perspectives in this field are discussed. Full article
