Zn(II)/La(III) Coordination Polymers Based on New Schiff Base Ligands for Highly Selective and Sensitive Detection of 2,4,6-Trinitrophenol.

In recent years, nitro explosives have posed a threat to national security and human health due to their hazard and environmental contamination. The rapid and effective detection of nitro explosives remains a challenge. In this work, a new Schiff base ligand HL was carefully designed and successfully synthesized, HL = 1,1'-((1,1')-(cyclohexane-1,4-diylbis (azanylidene)) bis (methylidene) bis (naphthalene-2-ol).

HKUST-1 nano metal-organic frameworks combined with ZnGaO:Cr near-infrared persistent luminescence nanoparticles for imaging and tumor chemodynamic and photothermal synergic therapy.

The multifunctional theranostic nanoplatform based on the combination of persistent luminescent nanoparticles (PLNPs) and metal-organic frameworks (MOFs) has both imaging and tumor therapeutic drug-loading functions, providing a new strategy for accurate and effective tumor diagnosis and treatment. Herein, the near-infrared (NIR) PLNP SiO@ZnGaO:Cr was combined with HKUST-1 MOFs to form a core-shell structure theranostic nanoplatform which possessed the triple function of autofluorescence-free NIR PersL bioimaging, tumor chemodynamic therapy (CDT), and tumor photothermal therapy (PTT). Also, the photothermal conversion efficiency reached 58.
