The Ir(III) compound Tp(Ms'')Ir(N2), that contains a pentadentate, doubly metalated 3-mesityl substituted tris(pyrazolyl)borate ligand, induces the cleavage of C-H and C-Cl bonds of CH2Cl2 to yield a highly electrophilic chlorocarbene Ir=C(H)Cl complex.

Functional pincer ligands that engage in metal-ligand cooperativity and/or are capable of redox non-innocence have found a great deal of success in catalysis. These two properties may be found in metal complexes of the 2,6-bis(pyrazol-3-yl)pyridine (bpp) ligands. With this goal in mind, we have attempted the coordination of 2,6-bis(5-trifluoromethylpyrazol-3-yl)pyridine (LCF3) and its Bu analogue 2,6-bis(5--butylpyrazol-3-yl)pyridine (LtBu) to Mo(0) by reactions with mixed phosphine/carbonyl complexes [Mo(CO)(MeCN)(PMePh)] 1-3 (1 ≤ ≤ 3).

Seventeen electronic states of the dication VH were characterized by the SA-CASSCF/icMRCI methodology using very extended basis sets; 11 were described for the first time. Potential energy curves were constructed and the associated spectroscopic parameters evaluated. Triplet and quintet states correlating with the V + H channel are thermodynamic stable.

The aromatic boron cluster B () has similar π bonding to CH, which is named "borozene". The B ligand has been observed to stabilize monovalent Ln(+I) in -LnB (Ln = La, Pr, Tb, Tm, and Yb) borozene complexes. Low-valency actinide complexes have been reported more rarely, and B may be one of the potential ligands.

An established concept to create radical intermediates is photoexcitation of a catalyst to a higher energy intermediate, subsequently leading to a photoinduced electron transfer (PET) with a reaction partner. The known concept of consecutive photoinduced electron transfer (con-PET) leads to catalytically active species even higher in energy by the uptake of two photons. Generally speaking, increased photon uptake leads to a more potent reductant.

Tumor hypoxia and elevated intracellular glutathione (GSH) levels significantly compromise the effectiveness of photodynamic therapy (PDT) in treating melanoma. In this study, we synthesized positively charged nanoparticles through a self-assembly method, incorporating photosensitizer verteporfin (VER), mitochondrial respiratory inhibitor atovaquone (ATO), and Fe. Subsequently, the nanoparticles were modified with sodium hyaluronate (HA) to obtain HA-ATO-Fe-VER nanoparticles (HAFV NPs).
