As a non-covalent fluorescence probe, in this study, salicylaldehyde azine (SA) was introduced as a sensitive fluorescence-based dye for detecting proteins both in 1-D and 2-D polyacrylamide electrophoresis gels. Down to 0.2 ng of single protein band could be detected within 1 h, which similars to that of glutaraldehyde (GA)-silver stain, but approximately four times higher than that of SYPRO Ruby fluorescent stain. Furthermore, comparative analysis of the MS compatibility of SA stain with SYPRO Ruby stain indicated that SA stain is compatible with the downstream of protein identification by liquid chromatography-tandem mass spectrometry (LC-MS/MS). Additionally, the probable mechanism of the SA stain was investigated by molecular docking. The results demonstrated that the interaction between SA and protein was mainly contributed by hydrogen bonding and hydrophobic forces.

The rapid and selective identification of microorganisms is of great significance for clinical therapy applications. To develop high performance probes for microbe determination, we systemically constructed series aggregation-induced emission (AIE) luminogens by modulating the structural planarity, the basicity of functional group, the length of linker moiety and the hydrophobicity based on our previous work. The detail structure-property relationship study based on experimental and theoretical observation revealed that: i) the planar skeleton is essential for probe insertion towards the cell wall via van n der Waals' force.

In this study, we have reported a novel 4-bromo-salicylaldehyde-diphenyl-azine (B-1), a new member of salicylaldehyde-diphenyl-azine (SDPA) family known for its excellent sensing properties. In contrast to the previously reported AIEgens, we found that the bromo-substitution at the 4th position of the salicylaldehyde moiety blue-shifted the emission by 10 and 15 nm as compared to the unsubstituted (Tong et.al 2017) and Bromo at the 5th position (Jain et.

As a valuable industrial chemical, thiophenol (PhSH) is poisonous, which can be easily absorbed by the human body, leading to many serious health issues. In addition, PhSH-triggered oxidative stress is considered to be related with the pathogenesis and toxicity of PhSH. Therefore, efficient methods for monitoring PhSH and ROS production induced by PhSH in living systems are very meaningful and desired.

Regulation of fluorescence and self-assembly of a salicylaldehyde azine-containing amphiphile by a water-soluble pillar[5]arene via host-guest recognition in water was realized. The fluorescence and the self-assembled aggregates of the bola-type amphiphile G can be tailored by adding different amounts of water-soluble pillar[5]arene (WP5). In addition, the emission property and self-assembly behavior of G and WP5 are responsive to pH conditions.

Some new transition metal complexes were prepared by reacting metal(II) salts with Schiff base azines, which were prepared via condensation of 5-(diethylamino) salicylaldehyde and hydrazine with pyrrole-2-carbaldehyde. Their structures were confirmed based on CHN, UV-visible, FT-IR, and EPR measurements. The complexes were also assessed for their antibacterial, antioxidant, and anticancer properties.
