The Front Cover shows that the luminophore Eu^III(hfa)₃ (hfa= 1,1,1,5,5,5-hexafluoroacetylacetonate) with chiral phosphine ligands exhibits intense circularly polarized luminescence (CPL) and magnetic circularly polarized luminescence (MCPL). These properties are enhanced due to the synergistic effect afforded by an external magnetic field and a P-centred chiral organic ligand.

封面：外部磁场对具有磷化氢手性的 EuIII(hfa)3 圆偏振发光的显着影响 (ChemPhysChem 17/2021)

封面显示具有手性膦配体的发光团 Eu ^III (hfa) ₃ (hfa= 1,1,1,5,5,5-六氟乙酰丙酮化物) 表现出强烈的圆偏振发光 (CPL) 和磁性圆偏振发光 (MCPL) . 由于外部磁场和以 P 为中心的手性有机配体提供的协同效应，这些特性得到了增强。更多信息可以在 Yoshitane Imai 和同事的文章中找到。
