In this study, fifty-one iconic tetrel bonding complexes were studied using the block localized wave function (BLW) method which can derive the self-consistent wavefunction for an electron-localized (diabatic) state where charge transfer is strictly deactivated.

Effective detection of antibiotics is essential for human health and environmental protection. A new type of water-stable fluorescent sensor was synthesized and characterized. The antibiotics in the water were detected by fluorescence spectroscopy. The complex presents excellent fluorescence quenching effect on nitroimidazole antibiotics with high selectivity and sensitivity and shows lower limits of detection with a wider linear range. The limit of detection (LOD) of the complex are 0.46 nM for ornidazole (ODZ), 0.73 nM for dimetridazole (DTZ), and 0.46 nM for metronidazole (MDZ). The K sv values are calculated to be 1.11 Â 10 4 M À1 for ODZ, 0.70 Â 10 4 M À1 for DTZ, and 1.10 Â 10 4 M À1 for MDZ. In addition, the sensor is recyclable and is expected to be used in the detection of nitroimidazole antibiotics in water. The luminescence quenching of Cd 2+ complex towards nitroimidazole antibiotics ascribed to the combination of electron transfer and energy transfer.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
