The rich optical spectrum with all transitions having the same LUMO as acceptor points to the (Bi)3 + core being electrophilic, and hence, facile SET reduction should be within reach. Indeed, cyclic voltammetry of 2 in dichloromethane reveals a reversible reduction wave at E1/2 = -0.95 versus Fc 0/+ , which we ascribed at the facile reduction to the corresponding fleeting π-allyl radical (Figure , and Supporting Materials).
