Synthesis and Properties of Novel Polymer Electronic-Phosphorescent Materials

Abstract:

In this paper, the method of Poly(N-vinylcarbazole)-co-di(2-(4-methylphenyl) (MSPD) Iridium(III))(NVK-MMI) preparation was carried out. The novel polymer were based on phosphorescent polymers involving a carbazole unit and an iridium-complex unit. The structure of the polymer were characterized by elemental analyses, FTIR, and 1H NMR. The UV-Vis absorption and photoluminescence (PL) spectra of the complexes were investigated. These results indicated they should be applied in the field of OLED. The NVK-MMI optical bandgap is calculated to be 2.25 eV. Cyclic voltammetry results confirm that the LUMO and HOMO levels of NVK- MMI were calculated as -3.02 and -5.27 eV, respectively.
