Mesoporous Silica Nanoparticles Capped with Graphene Quantum Dots for Potential Chemo–Photothermal Synergistic Cancer Therapy

In this study, mesoporous silica nanoparticles (MSNs) have been successfully capped with graphene quantum dots (GQDs) to form multifunctional GQD–MSNs with the potential for synergistic chemo–photothermal therapy. The structure, drug-release behavior, photothermal effect, and synergistic therapeutic efficiency of GQD–MSNs to 4T1 breast cancer cells were investigated. The results showed that GQD–MSNs were monodisperse and had a particle size of 50–60 nm. Using doxorubicin hydrochloride (DOX) as a model drug, the DOX-loaded GQD–MSNs (DOX–GQD–MSNs) not only exhibited pH- and temperature-responsive drug-release behavior, but using near-infrared irradiation, they efficiently generated heat to kill cancer cells. Furthermore, GQD–MSNs were biocompatible and were internalized by 4T1 cells. Compared with chemotherapy and photothermal therapy alone, DOX–GQD–MSNs were much more effective in killing the 4T1 cells owing to a synergistic chemo–photothermal effect. Therefore, GQD–MSNs may have promising applications in cancer therapy

Syntheses, Structures, and Physical Properties of Three Novel Metal−Organic Frameworks Constructed from Aromatic Polycarboxylate Acids and Flexible Imidazole-Based Synthons

Three novel interesting coordination polymers, [Cd3(SIP)2(bbi)5·3H2O]n (1), [Co3(SIP)2(bix)4(2H2O)·2H2O]n (2), and [Cd(2,5-pydc)2(bix)1.5·H2O]n (3) (SIP = 5-sulfoisophthalic acid monosodium salt; bbi = 1,1‘-(1,4-butanediyl)bis(imidazole); bix = 1,4-bis(imidazol-1-ylmethyl)-benzene; 2,5-pydc = pyridine-2,5-dicarboxylic acid), have been isolated under hydrothermal conditions and structurally characterized. Polymer 1 has a 3D complicated framework comprised of an infinite 1D ladder-like chain and 2D layer structure. Polymer 2 features a 3D hydrated framework with uncoordinated water molecules trapped in the pores. Polymer 3 is a 2D infinite layer framework, which is further interconnected by hydrogen-bond interactions to lead to a 3D supramolecular architecture. Compounds 1 and 3 exhibit medium-strong fluorescent emissions in the solid state at room temperature and could be significant in the field of photoactive materials

Flexible Ligand, Structural, and Topological Diversity: Isomerism in Zn(NO₃)₂ Coordination Polymers

Two new metal−organic frameworks (MOFs), [Zn(p-BDC)(m-bix)0.5][Zn(p-BDC)(m-bix)]·H2O (1) and [Zn(p-BDC)(m-bix)] (2) (p-BDC = terephthalate, m-bix =1,3-bis(imidazol-1-ylmethyl)benzene), were synthesized and characterized structurally. Both of the MOFs feature the interpenetrated two-dimensional (2D) → three-dimensional (3D) network motifs. In particular, complex 1 represents the second example of intertwining of different 2D coordination motifs, and complex 2 shows a 3-fold parallel interpenetrated framework. In addition, the spectroscopic, thermal, and fluorescence properties of complexes 1 and 2 are investigated
