This is the authors' abstract. We don't add key points for this paper.

Amorphous plastic disks (plastic matrix = PMMA: polymethylmethacrylate) containing Eu(III) coordination polymers connected with triangle amine linkers, [Eu(L1) 3 (tppa)] n and [Eu(L1) x (L2) y (tppa)] n (L1 and L2 = β‐diketonate, hfa: hexafluoroacetylacetonate, btfa: benzoyltrifluoroacetonate, +tfc: (+)‐3‐trifluoroacetylcamphorate, +hfc: (+)‐3‐heptafluorobutyrylcamphorate, tppa: tri‐diphenylphosphoryl‐4,4,4‐triphenylamine), are reported for fabrication of optical materials. Ligand‐mixed Eu(III) coordination polymers were prepared by mixing reactions of two coordination polymers, [Eu(L1) 3 (tppa)] n and [Eu(L2) 3 (tppa)] n in methanol. Prepared PMMA disks with Eu(III) coordination polymers (0.5 wt%) exhibit high transparency and effective photosensitized luminescence. The photosensitized energy transfer efficiencies of [Eu(L1) 3 (tppa)] n and [Eu(L1) x (L2) y (tppa)] n in PMMA were measured to estimate their luminescent performance. Ligand‐mixed Eu(III) coordination polymers, comprising both chiral–chiral and chiral–achiral combinations, exhibited photosensitized luminescence arising from asymmetric coordination geometries in PMMA disks. Luminescent plastic disks containing [Eu(L1) 3 (tppa)] n and [Eu(L1) x (L2) y (tppa)] n are demonstrated.
