Metal–organic polyhedra containing 36 and 24 folds of amide groups for selective luminescent recognition of natural disaccharides

An octa-nuclear bicoronal Ce-based triangular prism and tetra-nuclear molecular tetrahedron containing 36 and 24 folds amides within their main backbones were achieved and structurally characterized for the selective luminescent recognition of lactose and sucrose, respectively, over other related natural mono- and disaccharides.

A new fluorescent chemosensor for recognition of Hg2+ ions based on a coumarin derivative

A novel coumarin derivatives based fluorescent chemosensor CBH was designed and synthesized by Schiff base reaction, which was connected by 7-(N,N-diethylamino) coumarin-3-aldehyde and 3-methyl-2-benzothiazolinone hydrazone through C=N. X-ray single crystal structure analysis indicated that two aromatic groups of the CBH were almost in the same plane. It displayed enhancement of the fluorescent intensity and absorbance when the sensor CBH interacted with Hg2+ ions. The chemosensor CBH exhibited a good sensitive and selective recognition towards Hg2+ ions in the presence of other important relevant metal ions.
