Tetrahedral photoluminescent manganese(ii) halide complexes with 1,3-dimethyl-2-phenyl-1,3-diazaphospholidine-2-oxide as a ligand

Abstract

Photoluminescent Mn(ii) tetrahedral complexes characterized by intense emission in the green region were isolated from the reaction of MnX2 (X = Cl, Br, I) and the ligand 1,3-dimethyl-2-phenyl-1,3-diazaphospholidine-2-oxide.

Highly Emissive and Stable Five‐Coordinated Manganese(II) Complex for X‐Ray Imaging

“…According to the reported manganese(II) complexes, which are synthesized mainly through the coordination of P=O bond, the emitting‐color of manganese(II) complexes can be adjusted by the coordination number. [ 21–32 ] When manganese(II) ion is surrounded by four atoms giving Mn‐tetrahedral unit, the tetrahedral manganese(II) complexes exhibit green emission; while it exhibits red emission when manganese(II) ion is surrounded by six atoms in a Mn‐octahedral unit. [ 1,16,18,19–38 ] For instance, our group reported an efficient organic light‐emitting diodes based on green‐emitting phosphorescent neutral tetrahedral manganese(II) complex DBFDPO‐MnBr 2 with a PLQY as high as 81.4%.…”

Manganese(II) Thiocyanate Complexes with Bis(phosphine Oxide) Ligands: Synthesis and Excitation Wavelength‐Dependent Multicolor Luminescence

“…[26] Particular interest is devoted to Mn II halide complexes with phosphine oxide ligands. [25,[27][28][29][30][31][32][33][34][35][36][37] For instance, some of them, e.g. [Mn(Ph 3 PO) 2 Br 2 ], exhibit bright photo-and triboluminescence at ambient temperature.…”

Dimensional Structures and Electrocatalytic Activities of Platinum(II)–Palladium(II)–Manganese(II) Coordination Polymers Controlled by Chloride versus Bromide

“…This is remarkable because bromide possesses a coordination ability similar to or slightly lower than that of chloride . In fact, chloride and bromide have been shown to produce isostructural compounds in several coordination systems . Because protic organic solvents such as methanol and ethanol have commonly been used for reactions in the precedent systems, the use of water as a solvent for the syntheses of 2 Cl and 3 B likely contributes to the appearance of the different coordination behaviors of chloride and bromide to the Mn II centers.…”
