EurJOC [SOPhy]

Abstract : Micellar solutions of cetyltrimethylammonium bromide (CTAB) surfactant allow the spirocyclization of keto‐ynamides in an aqueous medium without recourse to transition‐metal catalysis, enabling access in water to naturally‐occurring aza‐spiro compounds with potential in drug discovery. The reaction was monitored by dynamic light scattering (DLS) and cryogenic transmission electron...[En savoir plus]

Dalton Transactions [BCB]

Abstract : Reversible turn-on fluorescent sensors of Cu(II) are of high interest for biological studies. We re-investigate a reported sensor, showing that turn-on occurs via irreversible Cu(II)-induced sensor oxidation only in the presence of acetonitrile. This prevents its application in biological studies and highlights the challenge of establishing a reversible Cu(II) turn-on...[En savoir plus]

Phys. Chem. Chem. Phys. [LCSOM]

Abstract : The CMD/AMLA mechanisms of cyclopalladation and the parent fictitious but challenging cyclonickelation of N,N-dimethylbenzylamine have been investigated by joint DFT-D and DLPNO-CCSD(T) methods assisted by QTAIM-based noncovalent interaction plots (NCI plots) and interacting quantum atoms (IQA) analyses, and the local energy decomposition (LED) procedure. Bader charges, NCI plots, IQA...[En savoir plus]

Phys. Chem. Chem. Phys. [POMAM]

Abstract : Spectral broadenings due to Dzyaloshinskii–Moriya interactions (DMI) were assessed with respect to the decoherence they induce through increased spin–spin interactions, as the role of DMI in developing magnetoelectric spin-chirality qubits is gaining recognition. The structurally related spin triangles [Fe3O(PhCOO)6(py)3]ClO4·py (Fe3) and [Cr3O(PhCOO)6(py)3]ClO4·0.5py (Cr3) were...[En savoir plus]

EurJIC [LCSOM]

Abstract : Two new trimetallic Cr‐Pd hemichelates containing a fluorenyl moiety and two trans arene‐bound Cr(CO)3 moieties were synthesized and fully characterized. Their molecular structures obtained by X‐ray diffraction analysis do not show major differences – in interatomic bond lengths within the Pd coordination sphere – when compared to previously reported bimetallic analogues. Theoretical...[En savoir plus]

JACS [CLAC]

Abstract : Nanostructures were built at the solid/liquid interface by self-assembly and/or coordination bonds. Metalloporphyrins bearing two external coordination sites and long alkyl chains allowed the self-assembly of the compounds on highly oriented pyrolitic graphite. After addition of a metal ion, long transition-metal linked porphyrin-nanoribbons were obtained and visualized by scanning...[En savoir plus]

Org. Biomol. Chem. [LSAMM]

Abstract: Despite the advantages of photodynamic therapy (PDT) over chemotherapy or radiotherapy such as low side effects, lack of treatment resistance and spatial selectivity inherent to light activation of the drug, several limitations especially related to the photosensitiser (PS) prevent PDT from becoming widespread in oncology. Herein, new folic acid- and biotin-conjugated PSs for...[En savoir plus]
