基于POSS核红光磷光材料的合成及性质研究

Synthesis and characterization of red phosphorescent materials based on polyhedral oligomeric silsesquioxane core

合成了两种含 POSS 的金属铱（Ir）配合物磷光材料 POSS‐7Cz‐Ir（L）2（q）（POSS‐1）和 POSS‐6Cz‐2Ir（L）2（q）（POSS‐2）。用1 HNMR、FT‐IR和MS对配体和磷光材料的结构进行了表征，并分别测定了两种磷光材料的紫外‐可见吸收光谱及光致发射光谱，通过热重和X RD分析了其稳定性。

Two new phosphorescent iridium（Ir） complexes containing polyhedral oligomeric silsesquioxane （POSS） core , such as POSS‐7Cz‐Ir （L ）2 （q ） （POSS‐1 ） and POSS‐6Cz‐2Ir （L ）2 （q ） （POSS‐2 ） , are synthesized and characterized by 1 HNMR , FT‐IR and MS . Their UV‐vis absorption and photoluminescence spectra are investigated . The thermal stability and morphology of POSS‐1 and POSS‐2 are also investigated by TG and XRD analysis .
