enching properties, association constants, and subsequent sugar
effect between two benzyl viologen quencher functionalized with
boronic acid groups (p-BV2+ and o-BV2+, Fig. 1) and an anionic
ruthenium(II) metal-ligand-complex (MLC) (Fig. 1). Ru MLC are today
known for their good spectrum characteristics (photo-stability,
large Stokes’ shift, long-wavelength emission, long-lifetime, etc.)
and are very promising as active material for the elaboration of
optical sensors [18].
