摘要

研究了单组分和二元离子液体的发光特性与纳米非均质性的关系。其阳离子为1-烷基-3-甲基咪唑和三己基（十四烷基）磷（[P666,14]+）。阴离子为[Cl]-、[Br]-、[MnCl4]2-和[MnBr4]2-。即使在液态，η[P666,14][Br] + [P666,14]2[MnBr4]二元混合物（η = 0.5, 1,2和4）在室温下也能发出绿光。在混合液体中，在小角和广角x射线散射图的低Q位置观察到纳米非均质性产生的预峰。随着温度的升高，IL混合物的发光强度增加，而不是几乎恒定的峰前强度。在403 K时，混合物的发光强度达到最大值（η = 0.5）。

Luminescence and Nanoheterogeneity in Manganese-Containing Ionic Liquid Mixtures.

The luminescence properties of single-component and binary ionic liquids (ILs) were investigated in relation to their nanoheterogeneities. The cations of the ILs were 1-alkyl-3-methylimidazolium and trihexyl(tetradecyl)phosphonium ([P666,14]⁺). The anions were [Cl]^-, [Br]^-, [MnCl₄]^2-, and [MnBr₄]^2-. Even in the liquid state, the binary mixtures of η[P666,14][Br] + [P666,14]₂[MnBr₄] (η = 0.5, 1, 2, and 4) emitted green light at room temperature. In the mixed liquids, the prepeak derived from the nanoheterogeneity was observed at a low Q position on the small- and wide-angle X-ray scattering patterns. With increasing temperature, the luminescent intensities of the IL mixtures increased, contrary to the almost constant prepeak intensity. The luminescence intensity maximum of the mixture (η = 0.5) was observed at 403 K.

期刊介绍： An essential criterion for acceptance of research articles in the journal is that they provide new physical insight. Please refer to the New Physical Insights virtual issue on what constitutes new physical insight. Manuscripts that are essentially reporting data or applications of data are, in general, not suitable for publication in JPC B.
