Two triple interpenetrating Zn(II)-based MOFs were studied in this paper. Named [Zn6(1,4-bpeb)4(IPA)6(H2O)]n (MOF-1) and {[Zn3(1,4-bpeb)1.5(DDBA)3]n·2DMF} (MOF-2), {1,4-bpeb = 1,4-bis [2-(4-pyridy1) ethenyl]benze, IPA Isophthalic acid, DDBA 3,3'-Azodibenzoic acid}, they synthesized by the hydrothermal method characterized stability tested. The results showed that MOF-1 had good acid-base solvent stability. Furthermore, excellent green fluorescence with different phenomena solvents, which was almost completely quenched acetone. Based on phenomenon, an acetone sensing test carried out, where detection limit of calculated to be 0.00365% (volume ratio). Excitingly, could also used as a proportional fluorescent probe specifically detect tryptophan, 34.84 μM. mechanism explained through energy transfer competitive absorption (fluorescence resonance (FRET)) internal filtration effect (IFE). For antibacterial purposes, minimum inhibitory concentrations against Escherichia coli Staphylococcus aureus 19.52 µg/mL 39.06 µg/mL, respectively, MOF-2 68.36 136.72 respectively.

Multifunctional Logic Operations Based Upon Congruent Ion Sensing Appended with a Strategic Molecular Device: Spectroscopic Approach

ChemNanoMat, Journal Year: 2024, Volume and Issue: 10(4)

Published: March 1, 2024

Abstract A multi‐responsive smart molecular system is constructed using a newly synthesized Salen molecule, 1,3‐bis((E)‐2,3,4‐trimethoxy benzylideneamino) propan‐2‐ol (TMBP), to selectively recognize the presence and absence of Cu 2+ ions aided by another selective metal ion, Zn . The emission efficiency non‐emissive probe significantly enhanced in , while improved probe‐Zn complex completely quenched upon interaction with Thus, acts as reporter molecule for detection co‐presence Comprehensive spectroscopic studies indicate that ion‐coordination reduces flexibility Schiff base unit extent photoinduced electron transfer which turn enhance fluorescence intensity. While d 9 system, induces paramagnetic quenching over through stable ground‐state complexation metal‐ligand charge transfer. results are translated into designing multifunctional smart‐molecular could function YES, NOT, INHIBIT, PASS 0, TRANSFER NOT logic gates. Finally, blueprint device proposed present relay sensing logical outputs would work in‐sync results.
