Tunable-Emissive Zeolite-Confined Silver Nanoclusters as a Rapid and Highly Sensitive Photoluminescent Sensor for Trace Water Detection in Organic Solvents.

Zeolite-confined silver nanoclusters (AgNCs/Zeolite) are highly promising luminescent materials. Nevertheless, the controlled synthesis of AgNCs/Zeolite composites with tunable luminescent responses remains a persistent challenge. In this study, highly luminescent AgNCs/Zeolite composites are developed through the counter-cations engineering strategy via confining AgNCs within the cages of FAUX with Na and Zn as the counter cations (Ag-FAUX(Na/Zn)), which show water-triggered switchable yellow/green tunable-emissive properties with PLQY up to 90% and high tolerance to chemical reduction.

Inclusion complex of GA-13316 with β-cyclodextrin: preparation, characterization, molecular modeling, and in vitro evaluation.

The inclusion complex of GA-13316 with β-cyclodextrin (β-CD) is one of a unique series of gibberellin derivatives possessed of potential anticancer activities. The complex with β-CD was characterized by means of UV, XRD, DSC, TG, (1)H, and 2D NMR spectroscopy. In addition, we investigated the main aspects of the interaction between GA-13316 and β-CD using both experimental and molecular modeling approaches.

Inclusion complex of GA-13315 with cyclodextrins: preparation, characterization, inclusion mode and properties.

GA-13315 (13-chlorine-3,15-dioxy-gibberllic acid methyl ester) was semi-synthesized by GA3 (gibberellic acid) as a potential anticancer drug. To pursue its promising application, cyclodextrin was used for forming complexes to overcome its drawbacks such as poor water solubility and stability. So, GA-13315/CD complexes were prepared with native β-cyclodextrin and its derivatives (hydroxypropyl-β-cyclodextrin (HPβCD)) and their inclusion complexation behavior, characterization and binding ability in both solution and the solid state was studied by means of UV, XRD, DSC, SEM, (1)H and 2D NMR spectroscopy.
