A laminated platinum-mesh working electrode positioned in an EPR fiat cell combined with a Ag pseudoreference electrode and a Pt counter electrode was used by Dunsch and coworkers for the in-situ study of C120O. The same group also performed simultaneous variable temperature EPR/UV-Vis-NIR experiments on Wurster s reagent and thianthrene. Similar cells using laminated ITO and gold working electrodes have also been reported. ... 

V,V,V,V-Tetramethyl-l,4-phenylenediamine dihydrochloride (Wurster s Reagent) [637-01-4] M 237.2, m 222-224°. Crystallise the salt from isopropyl or n-butyl alcohols, saturated with HCl. Treat... 

A method that utilizes the weak-link synthetic approach and hemilabile ligands, e.g., Al,Af -dimethyl-lV, -his[2-(diphenylphosphino)ethyl]-l,4-phenylenediamine, derived from M(V,ArAt -tetramethyl-l,4-phenylenediamine (Wurster s reagent), was used to prepare a new class of flexible, redox-active binuclear macrocycles <01IC2940>. 

Other redox-active receptors that have attracted recent attention are those such as compound 44, which is based on Wurster s reagent. This compound undergoes two reversible oxidations, with the first redox couple shifting to more positive potentials for the complex with K+ in acetonitrile.
