The invention discloses a polymer containing 9,9,10,10-tetraoxo-thianthrene seven-membered condensed ring unit, a preparation method and an application thereof. The general formula of the polymer structure containing 9,9,10,10-tetraoxo-thianthrene seven-membered fused ring unit is as follows, where x 1 、x 2 is the mole fraction of component unit components, satisfying: 0≤x 1 <1, 0<x 2 ≤1,x 1 +x 2 =1; n is a repeating unit, n=10-1000. The polymer has good thermal stability and high fluorescence quantum yield, and the existence of the sulfone unit can also improve the electron transport performance of the polymer. By adjusting the proportion of copolymerized units, the luminescence spectrum of the polymer can be adjusted, and polymers with different colors of luminescence can be obtained. This kind of polymer containing 9,9,10,10-tetraoxo-thianthrene seven-membered condensed ring unit can be used as an organic light-emitting material, and a polymer light-emitting diode can be prepared by a solution processing method.

The invention discloses thianthrene oxide-based yttrium complex phosphorescent luminescent materials and preparation methods thereof. The thianthrene oxide-based yttrium complex phosphorescent luminescent materials have general structural formulas shown in the description. The preparation methods comprise that an organic ligand containing a strong electron-withdrawing thianthrene oxide functionalgroup or other organic ligands and antimony trichloride undergo a reaction to produce a high electron injection transmission iridium complex phosphorescent material with phosphorescence quantum efficiency of 95% or more. The yttrium complex phosphorescent luminescent materials solve the problem that the traditional luminescent material has low phosphorescence quantum efficiency and weak electron injection transmission ability, and have an important application value in preparation of high performance organic light emitting diodes.
