Abstract
Sensor materials with multi-sensing properties are highly in demand. Especially non-invasive sensing materials for the application of heat management in temperature-sensitive chemical reactions like polymerization or enzymatic reactions are important, but also in-tissue non-intrusive sensors are strongly needed due to the number of chronic and inflammatory illnesses. To address this issue, a chemically and mechanically stable inorganic-organic hybrid material is synthesized, which responds to pH value and temperature adjustments with changed photoluminescence behavior. The inorganic-organic hybrid material persists of a new organosilane, 2-(3-(trimethoxysilyl)propyl)-1H-benzimidazole, and mesoporous silica as the inorganic part, which enables high loading of the organic benzimidazole units onto the surface and in the pores. Furthermore, the functionalization density of the hybrid material is adjusted, and the resulting optical properties are analyzed in detail. Further characterization methods are conducted to explore the composition, the porosity, and the sensing behavior of this inorganic-organic hybrid material.
