This paper describes the synthesis and characterisation of Ru-based, water-soluble complexes [RuII(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.
