Article Synopsis
- The study investigates the optical properties of four new trinuclear chalcogenolato bridged metal complexes, focusing on their near-infrared luminescence through various spectroscopy techniques and time-dependent density functional theory (TDDFT) calculations.
- All complexes show efficient luminescence between ∼880-1200 nm at low temperatures, with copper-titanium complexes maintaining significant luminescence at ambient temperature, achieving photoluminescence quantum yields of 9.5% and 4.8% for different wavelengths.
- The electronic transitions in these complexes are primarily localized on the metal and chalcogen atoms, with the core structure's composition influencing the absorption and emission characteristics.

The synthesis of calcium complexes ligated by three different chiral iminophosphonamide ligands, L-H (L=[Ph P{N(R)CH(CH )Ph} ]), L'-H (L'=[Ph P{NDipp}{N(R)CH(CH )Ph}]), (Dipp=2,6- Pr C H ), and L''-H (L''=[Ph P{N(R)CH(CH )naph} ]), (naph=naphthyl) is presented. The resulting structures [L Ca], [L' Ca], and [L'' Ca] represent the first examples of enantiopure homoleptic calcium complexes based on this type of ligands. The calcium complexes show blue-green photoluminescence (PL) in the solid state, which is especially bright at low temperatures.

A significant improvement in the selectivity of fullerene trifluoromethylation reactions was achieved. Reaction of trifluoroiodomethane with [60]fullerene at 460 degrees C and [70]fullerene at 470 degrees C in a flow reactor led to isolation of cold-zone-condensed mixtures of C60(CF3)n and C70(CF3)n compounds with narrow composition ranges: 6 < or = n < or = 12 for C(60)(CF3)n and 8 < or = n < or = 14 for C70(CF3)n. The predominant products in the C(60) reaction, an estimated 40+ mol % of the cold-zone condensate, were three isomers of C60(CF3)10.
