Periodic mesoporous organosilica based sensor for broad range mercury detection by simultaneous downshifting/upconversion luminescence

Abstract

Recent research in lanthanide materials has strongly contributed to the development of high-performance chemical sensors. However, the current reported high-responsive chemical sensors still have a limited detection range, restraining their...

Acetylacetone functionalized periodic mesoporous organosilicas: from sensing to catalysis

“…Embedded organic groups within the PMO framework act as efficient energy transfer antennas, sensitizing trivalent lanthanide ions (Ln 3+ ) and promoting luminescence. 13,23,24 The potential applications of such sensors span environmental monitoring, biological analysis, and other areas demanding accurate metal ion detection. 25 Despite this potential, research on lanthanide-based PMOs (LnPMOs) as chemical sensors remains limited, with only a few studies published in the late 2010s.…”

“…25 Despite this potential, research on lanthanide-based PMOs (LnPMOs) as chemical sensors remains limited, with only a few studies published in the late 2010s. 24,26–30 Among these, Eu-based materials have attracted significant attention for their potential in detecting copper ions (Cu 2+ ). 31–34 Eu-based materials exhibit strong initial fluorescence that undergoes significant quenching upon interaction with Cu ions, offering a highly sensitive and selective detection method for Cu in aqueous solutions.…”
