Summary: This paper reports a novel zinc ion sensor, 1o, synthesized by diarylethene and 2-aminobenzamide. When zinc ions were added, the fluorescence intensity of 1o increased by 11 times within 10 seconds, accompanied by a color change from dark blue to bright blue, and the detection limit was calculated to be 0.329 μM. The binding mode of 1o and zinc ions was determined to be 1:1 through various analytical techniques. Moreover, 1o was successfully developed into a fluorescent test strip for convenient and economical zinc ion detection in the environment.

Summary: The interfacial and aggregation behavior of sodium cholate and sodium deoxycholate in aqueous ionic liquid were studied. It was found that both IL and NaBF4 were able to reduce the critical micelle concentration of bile salts, with IL inducing the formation of larger aggregates by bile salts. Such systems are considered to have potential applications where the dual benefit of both a surfactant and an IL are warranted.

Summary: In this study, we synthesized 3-(1H-benzoimidazol-2-yl)-2-hydroxy-5-methyl-benzaldehyde (HBIA) from 2-(2-hydroxyphenyl)benzimidazole (HBI) and three Schiff bases from substituted amino benzoic acids. We investigated the photophysical properties of these compounds and found that their emission in the solid state is different due to the hydrogen bonding in their molecular structures. We also demonstrated that H(2)BIo, H(3)BIdm, and H(2)BIp can selectively detect Cu2+ in semi-aqueous medium.

Summary: In this study, two unsymmetrical and dipodal Schiff-Mannich combo ligands were synthesized and used for the selective detection of Zn2+ in semi-aqueous media. The probes showed a turn-on response to Zn2+ due to chelation-induced enhanced fluorescence and photo-induced electron transfer. Experimental studies showed that H2BBH and H3BSH could detect Zn2+ in solutions with low limit of detections. The structures of probe-Zn2+ ensembles were proposed by various methods. Moreover, the probes were successfully employed in the detection of Zn2+ in different samples.
