Abstract

<jats:title>Abstract</jats:title> <jats:p>Building on a previous design for a Ru-based dissolved N2 sensor, we report an adaptation that allows for reversible data storage. The N2 complex can be “fixed” and made stable across a range of pHs by the substitution of OH− with F− to form [RuII(F)(TMC)(N2)]+ (1, TMC = 1,4,8,11-tetramethyl-1,4,8,11-tetraazacyclotetradecane). The addition of Ca2+ and irradiation with light at high pH removes the F−, thereby regenerating the sensor in its reversible configuration.</jats:p>
