trinuclear diiminerhenium(I) tricarbonylcomplexes bridged by 1,3,5-tris(4-ethenylpyridyl)benzene (L1) or 1,3,5-tris(4-ethynylpyridyl)benzene (L2) have been synthesized and characterized. The L2-bridged complexes (group B) exhibit strong luminescence and long emission lifetimes in room-temperature solution which are typical of decay from 3MLCT excited states, while the L1-bridged complexes (group A)

ligands have been incorporated in dinuclear rhenium(I) diiminetricarbonyl complexes and provide anion recognition properties in these complexes. Furthermore, the related rhenium(I) complex featuring sulfonamide interacting sites that incorporate the highly chromophoric π-conjugated quinoxaline moiety has been prepared, characterized, and its photophysical properties were also studied.

A new luminescent rhenium(I) polypyridyl-based
receptor for a variety of inorganic anions has been designed and
synthesized and this artificial receptor shows high affinities for halides,
cyanide and acetate anions with binding constants as high as
104–105 M−1 and a detection
limit as low as 10−8 M in CH2Cl2
solution.

site and rhenium(I) tricarbonyl pyridine signaling units have been developed, and they display outstanding sensitivity and selectivity toward a variety of anionic species. These complexes are highly emissive in solution. Upon anion binding, the emission intensity was significantly quenched. The sensitivities of these complexes are so high that the emission intensity can be effectively quenched by as much
