The photoinduced electron transfer quenching of an anionic ruthenium(II) metal-ligand-complex (Ru(dpp(SO3Na))2(mcbpy)Cl2 by two boronic acid functionalized benzyl viologen (BV2+) derivatives has been investigated as well as their response to sugar. The electrostatic interaction between these two charge species lead to the formation of static quenching which is removed in presence of sugar due to the formation of a neutral zwitterionic quencher. Spectral data, quenching parameters and sugar titration curves are presented and discussed in term of future developments of optical sensors for sugar.

Three highly sensitive and selective switches for monosaccharides were composed by anionic polyelectrolyte PPPSO3Na and cationic viologen quencheres BBVs. The sensing processes of three ensembles (PPPSO 3Na/o-BBV, PPPSO3Na/m-BBV and PPPSO3Na/p-BBV) to common seven monosaccharides have been determined by fluorescence spectra at pH 7.4 buffer solution. The results show that the three sensing ensembles all embody higher selectivity and sensitivity for d-fructose with reversible "on-off-on" fluorescence response. The research results can provide a new mode for developing highly selective probes.
