An Effective Selenium-Based Fluorescence Chemosensor for Selective Recognition of Hg in Aqueous Medium: Experimental and Theoretical Studies.

We introduce a novel selenium-based compound [N-(Phenylcarbamoselenoyl) furan-2-carboxamide] for the optical and fluorimetric detection of Hg in an aqueous medium. The synthesized compound was characterized by different spectroscopic methods. The designed chemosensor FSU has shown a significant fluorescence quenching when Hg ions were added to the sensing medium.

Synthesis, characterization, theoretical, molecular docking and biological activity studies of Ru(II) (--cymene) complexes with novel aniline substituted aroyl selenoureas.

A sequence of aroyl selenourea ligands ( substituted by aniline and their Ru(II) (--cymene) complexes , [Ru(II) (--cymene) L] (L = monodentate aroyl selenourea ligand) have been synthesized and characterized the composition of the ligands and their metal complexes. The molecular structures of ligand and complex were also confirmed by single XRD crystal method. The single-crystal XRD study showed that aroyl selenourea ligand coordinates with Ru Se novel neutral monodentate atom.
