Glowing sweets! Three luminescent rhenium(I) polypyridine complexes have been modified with an α-D-glucose moiety. Their biomolecular binding, bacterial staining, and cellular-uptake properties have been examined (see figure). Various experimental results have indicated that glucose transporters play a very important role in the cellular uptake of these glucose complexes.
