Abstract

Redox "B" ess: Rational design of a new series of boron-functionalized Ni^III/Ni^IV-bis (dicarbollide) clusters results in a family of robust and tunable redox shuttles (see diagram; EDG and EWG denote electron-donating and -withdrawing groups, respectively). This offers a means to rationally control the redox properties in dye-sensitized solar cells (DSCs), leading to exceptionally high open-circuit voltages.
