新型双苯并咪唑钳形铂化合物的合成及其光致发光性质研究
Synthesis and photophysics of the new benzimidazol-based pincer platinum complexes
本文合成了一系列含有氯原子、碘原子、芳基炔烃和氮杂芳香化合物(吡啶衍生物和苯甲腈)辅助基团的钳形双苯并咪唑铂化合物。所得铂化合物在溶液和固态时均有明亮的发光现象，发射波长范围在510-540 nm。结果显示，随着辅助配体的变化，各种铂化合物单重态时的发光机理有较明显差异，除主要的配体间的IL 跃迁和金属到配体的MLCT跃迁外，铂碘化合物4还存在碘到配体的LLCT跃迁，而铂炔化合物5更是存在强的芳基炔烃到配体的LLCT跃迁。
series of bzimb platinum (II) complexes 3-11 using chloro, iodo, alkynyl and pyridine as the co-ligands are synthesized and characterized. Complexes 3-11 shows bright luminescence at room temperature with a structured high-energy emission band at general 510-540 nm. Moreover, their absorptions of complexes 3-5 and 8 can be primarily attributed to IL and MLCT transitions, mixed with minor LLCT character for 4. For the acetylide complex 5, its absorption is attributed to an admixture of the IL state, MLCT state and increased LLCT state.
