The design and synthesis of a mesoporous silica material functionalized with 2-chloroquinoline-3-carbaldehyde (SBA-Pr-NCQ) was developed, with the pore structure characterized by different techniques. Fluorescence features of SBA-Pr-NCQ were verified in aqueous media, showing good sensitivity and selectivity for Ag+ cations. The high detection limit and linear relationship between the fluorescence intensity of the modified structure (SBA-Pr-NCQ) and the concentration of Ag+ cations indicate its potential for sensing applications.
Design and synthesis of a mesoporous silica material functionalized with 2-chloroquinoline-3-carbaldehyde (SBA-Pr-NCQ) were developed. The pore structure of functionalized structure SBA-Pr-NCQ was characterized by different techniques. Fluorescence features of SBA-Pr-NCQ were verified by adding different metal ions in aqueous media and demonstrated good sensitivity and selectivity for Ag+ cations. The competition test displayed that the fluorescence response of the structure was specific for Ag+ cations. Additionally, the high detection limit of 7.6 x 10-6 M proved the good linear relationship between the fluorescence intensity of modified structure (SBA-Pr-NCQ) and the concentration of Ag+
