The mechanism of photoinduced symmetry-breaking charge separation in solid cyanine salts at the base of organic photovoltaic and optoelectronic devices is still debated. Here, we employ femtosecond transient absorption spectroscopy...

Weakly coordinating anions (WCAs) facilitate the stabilization and isolation of highly reactive and almost “naked” cations. Alkoxyaluminate-based WCAs such as [Al(OC(CF3)3)4]− ([pf]−) are widely used due to their synthetic accessibility...
