Abstract Nitrate is a naturally occurring ionic compound that is part of natureʹs nitrogen cycle. As a result of agriculture, disposal of human an‎d animal sewage an‎d industrial waste, the effect of increasing nitrate concentration on water quality is known as a critical issue in the future. Therefore, it is very important to develop robust an‎d powerful sensors to detect nitrate concentration. There is a growing interest in replacing conventional analytical methods with suitably selec‎tive chemical sensors. Sensors that allow continuous monitoring of nitrate concentration an‎d can be used in water treatment, agriculture an‎d various industries to prevent water pollution an‎d improve water quality. Among these, periodic mesoporous organosilicas (PMOs) synthesized from bridged silane precursors, due to their unique physical an‎d chemical properties, including high surface area, large pore volume, an‎d high thermal conductivity, have attracted much research. have attracted The unique feature of the architecture of PMOs is their potential applications that can be used as sensors. The incorporation of phenanthroline an‎d its derivatives into porous solids provides great application prospects for the detection of heavy metal ions an‎d other ions. In this work, we reported the direct synthesis of ordered mesoporous Phen-PMOs with phenanthroline content in the framework under green chemistry conditions. The application potential of Phen-PMOs as sensors for the detection of different types of nitrate ions was investigated
