Abstract

Building on a previous design for a Ru-based dissolved N ₂ sensor, we report an adaptation that allows for reversible data storage. The N ₂ complex can be "fixed" and made stable across a range of pHs by the substitution of OH ^- with F ^- to form [Ru ^II(F)(TMC)(N ₂)] ⁺ (1, TMC= l,4,8,11-tetramethyl-l,4,8,11tetraazacyclotetradecane). The addition of Ca2+ and irradiation with light at high pH removes the F ^-, thereby regenerating the sensor in its reversible configuration.
