S/Se differentiation through chalcogen bonding interactions is achieved in oxidized tetrathiafulvalenes with MeS- and MeSe-substituents.
Nucleophilic substitution reaction has been used as a tool to incorporate Se in ligands having imine functionality. Metal complexes of such ligands, i.e., Schiff bases, are used as homogeneous catalytic systems for a variety of organic reactions.
The Dzyaloshinskii–Moriya interaction (DMI), which only exists in noncentrosymmetric systems, plays an important role in the formation of exotic chiral magnetic states.
Photocatalytic reduction removes selenium from industrial brine through tunable reduction pathways to either Se0(s) or H2Se(g).
This review summarizes the design strategies, structure–property relationships, tunable photophysical properties, photoisomerization mechanisms, synthetic methods of aromatic Azo compounds, highlighting their biomedical prospects.
