N1 - The authors greatly appreciate financial support from the Russian Science Foundation, grant 19-79-00076 (the development of an OMS, experimental work) and the Ministry of Education and Science of the Russian Federation within the framework of state task No. 0778-2020- 0005 (data processing and calculations). The work was carried out using equipment of St. Petersburg State University Research Park (Magnetic Resonance Centre, Centre of Chemical Analysis and Materials Research, and Optical and Laser Materials Research Centre).

N2 - Advances in material science, optics, and electronics allow the creation of simple and low-cost measuring devices for various applications. In the present work, an optical multisensor system was designed using Cu(I) molecular emitters as a light source. The major advantage of this measuring platform is the ability to adjust the source wavelength for a particular analytical task. Here the possibility to measure fluoride and phosphate content in natural and tap waters using the optical setup with a UV flashlight as an excitation source for Cu(I) complexes has been demonstrated. The root mean-square prediction error (RMSEP) value for analyzed water samples attained with partial least-squares (PLS) regression method was 0.07 mg/L for both fluoride (0–0.4 mg/L concentration range) and phosphate (0–0.96 mg/L). These values are comparable with those for standard analytical techniques. This proof of concept study confirms the possibility of constructing adjustable optical multisensor systems based on Cu(I) emitters for real-life applications.
