Merging Dual Antenna Effect with Target-Insensitive Behavior in Bimetal Biligand MOFs to Form Efficient Internal Reference Signal: Color Tonality-Ratiometric Designs

ACS Materials Letters, Journal Year: 2024, Volume and Issue: 6(6), P. 2339 - 2349

Published: May 14, 2024

The construction of a highly luminescent, stable, and target-insensitive internal reference signal is significant in ratiometric color tonality applications. Improvement the antenna effect, efficient mechanism that enhances luminescence emission via sensitization, an effective route to obtain bright luminescence. Additionally, manipulation crystal structure morphology key issue control reactivity, especially metal–organic frameworks (MOFs). In present work, novel red emitter Eu/Zn bimetal biligand MOF (UoZ-5) was synthesized used as signal. A dual-antenna from triplet states (T1) ligands 5Do Eu3+ ion, observed explained on basis energy levels. With UoZ-5 serving reference, blue-emitting carbon quantum dots (CQDs) selective for Ag+ ions nonfluorescent composite, CQDs@Ag+, probe vitamin B1, tonality-based platform analysis were developed.

The trace detection of biomarkers in real samples has profound a most important significance the early diagnosis and daily monitoring diseases. Based on ligand pre‐design strategy, novel 3D CuMOF, with formula {[Cu 4 (BTPB)( μ 2 ‐OH) (H O) 5 ]·3H O} n , was fabricated by using hexacarboxyl 1,4‐bis(2,4,6‐tricarboxylpyrid‐5‐yl)benzene 6 BTPB) tetranuclear {Cu (COO) ( } SBUs. Benefiting from robust framework unique luminescence performance, prepared CuMOF displays great potential as dual‐responsive efficient luminescent sensor “turn‐off” 3‐nitrotyrosine (3‐NT) biomarker “turn‐on” detecting anthrax dipicolinic acid (DPA), limits (LOD) for 3‐NT DPA being 110.8 ng/ml 85.2 ng/ml, respectively. Additionally, practicality compatibility such developed sensors were verified quantifying diluted serum urine satisfactory recoveries. Further, theoretical calculations energy levels well spectral overlap between analytes conducted to elucidate possible sensing mechanisms. This work demonstrated that MOFs‐based are evolving an efficacious equable approach samples.
