Research On Polymer White Light Materials And Devices Based On ?-diketone Rare Earth Complexes

As we all know,the rare earth ?-diketone complexes have superior optical properties and excellent physical properties,so this paper is aimed to build some new type white polymer light-emitting materials and devices in regard to this complexes.These novel materials possess excellent optical properties and good process ability,so it can be expected that it must be a new field in WLED in the future.First,all the rare earth complexes in this paper include the ?-diketone ligands neither HDBM(Bibenzoyl methane)or HBA(1-Benzoylacetone)and the secondary ligands 5-Br-2,2'-bpy or 4-vinyl-Py or Zn(L2)(HL2= N,N'-Bis(salicylidene)cyclohexane-1,2-diamine),the ternary solid complexes of rare earth was distributed into three series:(Series ?)Ln(BA)3(5-Br-2,2'-bpy)](Ln = La,1;Ln = Eu,2;Ln = Tb,3;Ln = Gd,4);(Series ?)Ln(DBM)3(4-vp-2,2'-bpy)(Ln = La,5;Ln = Eu,6;Ln = Tb,7;Ln = Gd,8);(Series ?)Zn(L2)(OAc)Ln(DBM)2](Ln = La,9;Ln = Eu,10;Ln = Tb,11;Ln = Gd,12).These molecular structures were characterized by FT-IR,1H NMR,EA,X-ray.And if the structures are correct,and then the UV-Vis absorption spectra and optical properties were,well researched.Finally,a series of hydrid white light-emitting materials PMA@2@3?PVK@2@3?Poly(6-co-NVK-co-8)and PMMA@10@[ZnL1(Py)]was synthesized by the complex monomers.And a white organic light-emitting devices(WOLED)were obtained by the hybrid materials.The metallopolymers can also be characterized by IR,1HNMR,EA,PXRD,GPC,TG,DR,Photoluminescence and Electroluminescence,respectively.
