“…Several instances of viologens serving as fluorescence quenchers for organic dyes, porphyrins, and polymers have been reported. Due to their electron-deficient nature, viologens function as acceptors in many charge-transfer (CT) complexes 11a.…”

Boronic Acid-Based Bipyridinium Salts as Tunable Receptors for Monosaccharides and α-Hydroxycarboxylates

et al. 2007

Several novel diboronic acid-substituted bipyridinium salts were prepared and, using a fluorescent reporter dye, were tested for their ability to selectively bind various monosaccharides and alpha-hydroxycarboxylates in an aqueous medium. The fluorescence sensing mechanism relies on the formation of a ground-state charge-transfer complex between the dye and bipyridinium. An X-ray crystal structure of this complex is described herein. Glucose selectivity over fructose and galactose was achieved by designing the bipyridinium-based receptors to be capable of attaining a 1:1 receptor/substrate stoichiometry via cooperative diboronic acid binding.

Ein gerichteter Elektronentransfer zwischen identischen Chromophoren durch die polyelektrolytischen mehrschichtigen Wände hohler Mikrokapseln kann photochemisch induziert werden (siehe Bild). Ermöglicht wird dies durch Einfügen von Pyreneinheiten in einen Film und Aufbau eines Polaritätsgradienten über Nanometerdistanzen. PV=Polyviologen; PSS‐Py=Polystyrolsulfonsäure/Pyren; PDADMAC=Poly(diallyldimethylammoniumchlorid).

Vectorial electron transfer between identical chromophores across the polyelectrolyte multilayer walls of hollow microcapsules can be photoinduced (see picture). This is achieved by inserting pyrene units in sufficiently high concentration into a film and setting up a polarity gradient over nanometer dimensions along which the charge transfer is directed. PV=polyviologen; PSS‐Py=polystyrenesulfonic acid/pyrene; PDADMAC=poly(diallyldimethylammonium chloride).
