Abstract

This study presents a new class of coordination polymers synthesized from 1,2,4,5-tetrakis(diphenylphosphino)pyridine and trivalent Eu(III), Tb(III), and Gd(III) ions. The synthesized polymers exhibit a unique one-dimensional periodic structure enabled by the bridging chelate nature of the ligand, and a noteworthy luminescent efficiency. Terbium and Europium complexes demonstrate high quantum yields and high purity luminescence colors. They are therefore promising materials for photonic devices such as OLEDs, where high-intensity monochromatic emission is required.

1,2,4,5-四akis（二苯基膦）吡啶与Eu(III), Tb （III）和Gd（III）的新配位聚合物。合成及发光性能

本文研究了一类由1,2,4,5-四（二苯基膦）吡啶与三价Eu（III）、Tb（III）和Gd（III）离子合成的新型配位聚合物。由于配体的桥接螯合性质，合成的聚合物具有独特的一维周期结构，并且具有显著的发光效率。铽和铕配合物表现出高量子产率和高纯度的发光色。因此，它们是光子器件（如需要高强度单色发射的oled）的有前途的材料。
