Reaction of o-mesitylsulfonylhydroxylamine with Ph2Se results in the selenimidium cation [Ph2SeNH2]+, which in turn acts as a source of Ph2SeNH; bromination, followed by treatment with Ph2Se, yields [Ph2SeNSePh2]+.
Solution studies of trimetallic lanthanide luminescent anion sensors: towards ratiometric sensing using an internal reference channel
Sally E. Plush and Thorfinnur Gunnlaugsson,
Dalton Trans., 2008, 3801
DOI: 10.1039/b805610b
The syntheses and potentiometric and spectroscopic investigations of three new trimetallic lanthanide complexes are described. These complexes function as luminescent anion sensors where in the case of the mixed Tb(III)–Eu(III) complex, the Eu(III) emission was enhanced while the Tb(III) emissions quenched upon recognition of malonic acid at pH 6.5.

The methodology used here for the synthesis of multinuclear alkynylated Zn(II)-salophen complexes is simple and efficient. With regard to their photophysical properties, introduction of ethynylfluorene groups in salophen moieties and dialkoxyl groups in the bridging moiety significantly improve the quantum efficiency of these complexes.
