Abstract

This paper describes the synthesis and characterisation of Ru-based, water-soluble complexes [Ru^II(X)(Y)(TMC)] (X, Y = H₂O or OH; TMC = 1,4,8,11-tetramethyl-1,4,8,11-tetraazacyclotetradecane) capable of behaving as colorimetric, water-soluble, dissolved N₂ sensors. Unlike previous water-soluble N₂ complexes, binding to N₂ is both reversible and pH-switchable, i.e., binding can be switched on at high pHs and switched off at low pHs. Sensing can be performed at partial pressures of N₂ as low as 0.01 MPa.
