Herein, magnetic circularly polarized luminescence (CPL) (MCPL) spectroscopy was conducted to analyze an EuIII(hfa)3 complex with three chiral PIII-ligands. Resultantly, (R)-chirality luminophores with S-up orientation and (S)-chirality luminophores with N-up orientation were observed to possess symmetrical mirror image spectra, i. e., they were enantiomers. Similarly, the (R)-chirality luminophores with N-up orientation and the (S)-chirality luminophores with S-up orientation were also enantiomers. Contrarily, (R)-S-up and (S)-S-up were diastereomers and did not possess a mirror-image relationship. Likewise, (R)-N-up and (S)-N-up were diastereomers. The J-dependency of gMCPL and gCPL datasets suggested that the N-up/S-up external magnetic field, with the aid of chiral PIII-ligands, increased the gMCPL values by two- to sixteen-fold and modulated the gMCPL signs at J=1–4. Additionally, the origins of the nonideal mirror-symmetric CPL and MCPL spectral characteristics of EuIII(hfa)3 with three chiral PIII-ligands were discussed in terms of parity (space-inversion, P)-symmetry, time-reversal (T)-symmetry, and PT-symmetry laws.

外磁场对具有磷化氢手性的EuIII(hfa)3圆偏振发光的显着影响
在此，进行磁性圆偏振发光（CPL）（MCPL）光谱以分析具有三个手性P III -配体的Eu III (hfa) 3复合物。作为结果，（- [R ）与S-向上取向和（-chirality发光体小号观察）-chirality发光体用的N-up取向具有对称镜像光谱，我。即，它们是对映异构体。类似地，（- [R）-chirality发光体用的N-up取向和（小号）-chirality发光体与S-向上取向也对映体。相反，( R )-S-up 和 ( S)-S-up 是非对映异构体，不具有镜像关系。同样，( R )-N-up 和( S )-N-up 是非对映异构体。g MCPL和g CPL数据集的J依赖性表明 N-up/S-up 外部磁场在手性 P III配体的帮助下，将g MCPL值增加了2 到 16 倍并调制了g MCPL在J = 1–4处签名。此外，具有三个手性 P III的 Eu III (hfa) 3的非理想镜像对称 CPL 和 MCPL 光谱特性的起源-配体根据奇偶性（空间反转，P）对称性、时间反转（T）对称性和PT对称性定律进行了讨论。
