Luminescent copper(I) halide complexes with bi- and tridentate rigid ligands have gained wide research interests. In this paper, six tetracoordinate dinuclear copper(I) halide complexes, Cu2X2(ppda)2 [ppda = 2-[2-(dimethylamino)phenyl(phenyl)phosphino]-N,N-dimethylaniline, X = I (1), Br (2), Cl (3)] and Cu2X2(pfda)2 [pfda = 2-[2-(dimethylamino)-4-(trifluoromethyl)phenyl(phenyl)phosphino]-N,N-dimethyl-5-trifluoromethylaniline, X = I (4), Br (5), Cl (6)], were successfully prepared and systematically characterized on their structures and photophysical properties. Complexes 1-5 have a centrosymmetric form with a planar Cu2X2 unit, and complex 6 has a mirror symmetry form with a butterfly-shaped Cu2X2. Solid complexes 1, 4, and 5 emit delayed fluorescence at room temperature, intense blue to greenish yellow (λmax = 443-570 nm) light, and their peak wavelengths are located at 443-570 nm with microsecond lifetimes (τ = 0.4-19.2 μs, φPL = 0.05-0.48). Complexes 2, 3, and 6 show prompt fluorescence, very weak yellowish green to yellow (λmax = 534-595 nm) emission with peak wavelengths at 534-595 nm, and lifetimes in nanoseconds (τ = 4.4-9.3 ns, φPL a maximum EQE up to 0.17%, and luminance reaching 75.52 cd/m2.

Highly emissive copper(i) halide nanoclusters showing thermally activated delayed fluorescence (TADF) have been paid much attention, but rarely reported so far. Herein, a hexanuclear copper(i) iodide cluster containing a tridentate N?P?N ligand, [Cu6I6(ppda)2] {ppda = 2-[2-(dimethylamino)phenyl(phenyl)phosphino]-N,N-dimethylaniline}, was synthesized. All six copper atoms are four-coordinate, including four CuPNI2and two CuI4units. This complex exhibits intense white emission in the powder state at room temperature and shows a peak at a wavelength of 535 nm (FPL= 0.36) with a microsecond lifetime (t= 4.4 μs). Emission colors can be largely tuned from blue to white to yellow, from the crystal to powder to film state at 297 K. The emission of [Cu6I6(ppda)2] originates from a combination of MLCT and XLCT transitions. This complex showed good thermal stability. A solution-processed, nondoped device of complex [Cu6I6(ppda)2] exhibits stable yellow emission with the CIE coordinates (x,y) of (0.43, 0.51). [Cu6I6(ppda)2] also shows reasonable photocatalytic H2evolution activity under visible-light irradiation.

N,N-dialkylarylamines and N,N-dialkylbenzylamines are lithiated with n-butyllithium (n-BuLi) under the assistance of tetramethylethylenediamine (TMEDA) in the ortho-position.According the Eqs. (1) and (4) triarylphosphines (30-50percent) are obtained. 1-(N,N-dimethylamino)-naphthalene and N,N-dimethyl-1-(1-naphthyl)-ethylamine 18 are lithiated in the 8-position.In N,N-dimethyl-1-(2-naphthyl)-ethylamine 19 the 1- and 3-position is lithiated in nearly equal amount.Experiments to introduce lithium twice into the model compounds 28-30 are without success.
