Thermally activated delayed fluorescence in luminescent cationic copper(i) complexes

“…A handful of reviews and recent reports that cover the photophysical and photochemical properties of the other types of Cu(I) TADF complexes are available in the literature. 19,22,47,[110][111][112][113][114][115][116][117][118][119][120][121][122][123][124] Several examples of [Cu(N^N) 2 ] + and [Cu(N^N)(P^P)] + complexes that exhibit TADF have been reported in the literature. 57,[129][130][131][132][133][134][135][136][137][138][139][140] The photophysical properties of some of these complexes are reported in Table 1.…”

New Approach toward Dual-Emissive Organic–Inorganic Hybrids by Integrating Mn(II) and Cu(I) Emission Centers in Ionic Crystals

“…Herein, we report a new general approach to design a remarkable family of DE inorganic–organic hybrid materials by blending [Cu x I y ] ( y − x )– and Mn­(II) emitting centers within a single ionic structure (Figure ). The individual Cu­(I) and Mn­(II) complexes are considered now as promising low-cost luminescent materials for numerous applications, − including the general lighting industry. , They often demonstrate an efficient and tunable phosphorescence in deep-blue to NIR spectral range, ,,− as well as stimuli-responsive (“smart”) luminescence, triboluminescence, − circularly polarized luminescence, , and nonlinear optical effects . Moreover, low toxicity and excellent thermal robustness are inherent to Cu­(I) and Mn­(II) compounds.…”

Halogen-induced core structural evolution of four dinuclear copper(i) luminescent coordination compounds

“…The rational design and synthesis of luminescent Cu(I) compounds have attracted increasing attention 1 owing to their chemically interesting structural features as well as potential for applications in solar energy conversion, luminescence-based sensors, display devices, and probes of biological systems. [2][3][4][5][6][7][8] It is well-known that the photochemical processes are generally accompanied with geometry changes of donor-acceptor system, involving charge separation and recombination. The structural rearrangement of a single Cu(I) coordination geometry from pseudo-tetrahedral to square planar in the excited state of corresponding compounds can lead to low quantum yields in solution derived from the major quenching pathway of the emission, facilitating solvent coordination and exciplex formation.…”
