Summary: The lysozyme binding affinity and electronic properties of [ReX (CO)(3)(terpy-κN-2(1),N-2)] (X = Br− and triazolate(COOCH2CH3,CF3)) were reported, with the triazolate compound showing a red shift of the MLCT band in less polar solvents possibly due to negative solvatochromism. The triazolate complex was prepared through a [3 + 2] cyclo-addition click reaction, while the bromo compound reacted with lysozyme forming adducts with Re(CO)(3)(+) fragments.

Summary: This study synthesized and characterized twelve Re(i) tricarbonyl diimine complexes with thiotetrazolato ligands. The tetrazolato ligand can bind to the Re(i) center through either the S atom or the N atom, with most complexes being bound to the N atom. In solution, the complexes exist as an equilibrating mixture of linkage isomers. The complexes exhibit photoluminescent properties, with emission wavelengths dependent on the nature of the diimine ligand.

Summary: Chemotherapy with platinum drugs is a common treatment for cancer, but resistance and toxic side effects limit its effectiveness. Researchers have discovered a new class of oxo-rhenium(V) complexes that have higher antitumor activity and can overcome resistance. These complexes accumulate in mitochondria, disrupt mitochondrial membrane potential, and increase reactive oxygen species, leading to cancer cell death.

Summary: Organelle-targeted photodynamic therapy (PDT) using a tricarbonyl Re(I) complex (Re-BDP) was shown to effectively kill cancer cells by generating toxic reactive oxygen species (ROS) in the endoplasmic reticulum (ER). Re-BDP exhibited strong absorbance and high singlet oxygen quantum yield, and preferentially accumulated in the ER. Upon visible light irradiation, Re-BDP showed high phototoxicity and induced caspase-dependent apoptosis accompanied by mitochondrial dysfunction. This study highlights the potential of developing efficient organelle-targeted phototherapeutic agents by conjugating metal complexes and organic chromophores.

Summary: A one-step synthesis method of paramagnetic Re(I) compounds was developed by reacting [Re(CO)(5)Br] with spin-labeled N-donor heterocycles. Nitronyl nitroxide derivatives of 1H-imidazole (L-1), 1H-pyrazole (L-2), di (1H-pyrazol-1-yl)methane (L-3), and 4-methyl-2-(1H-pyrazol-1-yl)quinoline (L-4) could replace two CO molecules in [Re(CO)(5)Br], leading to the formation of paramagnetic fac-[Re(CO)(3)(L-i)(n)Br]center dot xSolv complexes. The coordination of paramagnetic L-1-L-4 ligands to Re(I) was confirmed by single crystal XRD studies. Magnetic behavior analysis showed that complexes 1-3 were biradicals, while complex 4 was a monoradical. The therapeutic properties of Re(I) and the contrasting characteristics of nitroxide radicals make [Re(CO)(3)(L-i)(n)Br] valuable model objects for material design in theranostics.

Summary: By hybridizing TiO2 photocatalyst with CaCO3 as the wall material and using linseed oil as the core material, self-cleaning and self-repairing microcapsules were produced using in-situ precipitation. The microcapsules were evaluated for their morphology, chemical composition, thermal stability, and self-cleaning and self-repairing properties. Results showed that the microcapsules had a rough and spherical surface, along with excellent thermal stability and repeatability. Increasing the dosage of microcapsules significantly increased the degradation rate of methylene blue, while the self-repairing effect of micro-cracks became more evident. The optimal microcapsule dosage was found to be 7.0 wt%.
