Efficiently luminescent cuprous iodide complexes supported by novel N^P-chelating ligands: Synthesis, structure and optoelectronic performances

Syntheses, Crystal Structures and Photophysical Properties of Dinuclear Copper(I) Complexes Bearing Diphenylphosphino‐Substituted Benzimidazole Ligands

“…Additionally, the dihedral angles between the N−Cu−P plane and the I−Cu−I’ plane are of 87.487°( 1 ), 86.789°( 2 ) and 85.932°( 3 ), respectively. The Cu−P and Cu−I bond lengths of the complexes are consistent with the literature values [4b,18] . It is interesting to note that the Cu−N bond distance (2.1204(15) Å) in 2 is slightly shorter relative to that of 1 (2.142(3) Å) and 3 (2.1329(17) Å), implying that the methoxy substituent on the 2‐phenyl ring has an expected electronic effect.…”

Heteroleptic copper(i) complexes [Cu(dmp)(N^P)]BF4 for photoinduced atom-transfer radical addition reactions

“…[53][54][55] The synthesis, electrochemical and photophysical properties of bi-, or multi-nuclear Cu(I) halide complexes with heterobidentate imine-phosphine (P^N) ligands have likewise been investigated. [56][57][58][59][60][61][62] Recently, the groups of Suzuki, Tschierlei, and Karnahl reported homoleptic copper(I) complexes with two phosphinooxazoline (N^P) ligands, [63][64][65] which displayed high stability during photocatalytic hydrogen production, enabling photocatalytic activity for more than 24 h. However, heteroleptic bis-chelate mononuclear copper(I) complexes [Cu(N^N)(N^P)] + bearing one imine-phosphine and one diimine ligands have less been reported. Prompted by our continuous interest in visible-light photoredox catalysis, [66][67][68] we have synthesized phosphinopyrazolyl ( phpz) N^P ligands R 1 R 2 C 3 HN 2 PPh 3 (R 1 = R 2 = H (1a); R 1 = H, R 2 = Me (1b); R 1 = H, R 2 = Ph (1c); R 1 = R 2 = Me (1d)) with variation in the R 1…”

Fine Emission Tuning from Near-Ultraviolet to Saturated Blue with Rationally Designed Carbene-Based [3 + 2 + 1] Iridium(III) Complexes

“…Organic light-emitting diodes (OLEDs) have drawn extensive interest due to their excellent applications in displays and lighting. − Among various kinds of emitters, high-efficiency phosphorescent complexes such as those with iridium­(III), − platinum­(II), − copper­(I), − and gold­(I) − metal centers have been widely reported. The presence of these heavy-metal centers can lead to effective spin–orbital coupling, which allows the triplet emitters to harvest both singlet and triplet excitons, achieving 100% internal quantum efficiency.…”
