WebJan 15, 2024 · Notably, the same-size yellow boxes represent the pairing with a specific counterion, either a monovalent or a divalent one, in the ion-exchange membrane (IEM). For instance, a paired divalent counterion occupies two pairing sites (two yellow boxes), while a monovalent counterion takes only one yellow box.

3.2: Counterions - Chemistry LibreTexts
In chemistry, a counterion (sometimes written as "counter ion", pronounced as such) is the ion that accompanies an ionic species in order to maintain electric neutrality. In table salt (NaCl, also known as sodium chloride) the sodium ion (positively charged) is the counterion for the chloride ion (negatively charged) and vice versa. WebMar 1, 2024 · A bulky counterion paired to HCs was found to elicit substantial improvements in absorptivity (7‐fold), brightness (14‐fold), and spectral profiles in water, addressing a notorious quenching ... WebJul 14, 2024 · Drastically distinct transient dipole-moment evolution is observed as a result of the counterion reorganization arising from a contact ion pair. Differences in a contact-separated versus solvent-separated ion pair are manifested in the excited-state electronic structure, relaxation dynamics, and photoinduced electron-transfer kinetics. swoosh background
