From a biological point of view, Schiff base probes containing fluorescent groups are chemically modified to provide an effective method for the detection of amino acids. According to this method, three molecular probes containing Schiff base and hydroxyl group have been designed and synthesized. UV‐Vis and fluorescent data indicated that compound 2 showed strong sensitivity and high selectivity for arginine (Arg) among normal twenty kinds of amino acids. In addition, compound 2 displayed high combining ability with Arg and low cytotoxicity in MCF‐7 cell from 0 to 150 μg/mL. The above results showed the synthesized probes also can be used a biosensor for the Arg detection in vivo.

Applied Sciences

A series of new compounds (1-12) containing 1,5-diaza-fluorenone, 1,10-phenanthroline-5,6-dione, ferrocene-1,1ʹ-dione, anthracene-9-carbaldehyde have been synthesized and optimized. The nanomaterials were also developed successfully. ) by theoretical investigation, UV-vis, and fluorescence experiments, and compound 6 displayed the strongest binding ability for AcO − ion among the synthesized compounds. Theoretical investigation analysis revealed that the intramolecular hydrogen bond existed in the structure of compound 6 and the roles of molecular frontier orbitals in molecular interplay. In addition, compound 6 showed wide antibacterial activity for colon bacillus, typhoid bacillus, and Pseudomonas aeruginosa, and inferior activity for hay bacillus and Staphylococcus aureus. This series of acylhydrazone nanomaterials showed double properties, anion binding ability, and antibacterial activity.

New phenanthroline derivatives containing phenol groups have been synthesized and optimized. The nano-material involved bromine substituent was also developed which in the ortho-position of benzene ring. Their binding properties were evaluated for various biological anions (F -, Cl -, Br -, I -, AcO -and H 2 PO 4 -) by theoretical investigation, UV-vis, fluorescence, 1 H NMR titration experiments. These compounds all showed strong binding ability for AcO -without the interference of other anions tested. The anion binding ability could be regularized by electron push-pull properties of the ortho-or para-substituent on benzene. Theoretical investigation analysis revealed the effect of intramolecular hydrogen bond existed between -OH and other atoms in the structure of these compounds.
