【摘要】 以2-氯喹啉和苯硼酸为原料,在四（三苯基膦）钯作催化剂下反应得到主配体2-苯基喹啉（pq）,之后pq与水合三氯化铱在乙二醇单乙醚溶剂中反应得到铱的氯桥二聚体（pq）₂Ir（μ-Cl₂）Ir（pq）₂,然后在碱性条件下和乙酰丙酮反应合成出高效磷光红光材料二（2-苯基喹啉-C2,N’）（乙酰丙酮）合铱（Ⅲ）Ir（pq）₂（acac）。通过元素分析、红外光谱、核磁共振谱(¹ H NMR、¹³C NMR)、质谱和单晶X射线衍射等表征手段确定了分子结构,利用紫外-可见吸收光谱和光致发光光谱对其光物理性能进行了测试。结果表明,Ir（pq）₂（acac）为电中性八面体配合物,Ir—O键的平均长度为0.21741（18）nm,而Ir—C键的平均长度0.1983（3）nm,Ir—N键的平均长度为0.2079（2）nm,在600nm处出现了较强的红光发射,其合成产率>95%,该方法适于Ir（pq）₂（acac）的小批量制备。更多还原

【Abstract】 A new chemical process was developed for bulk-synthesis of bis（2-phenylquinolyl-N,C2’）（acetylacetonate）Iridium（Ⅲ）,an organometallic light-emitting molecule for OLED.The process involved three chemical reactions starting from 2-chloro-quinoline.The reaction of 2-chloro-quinoline with phenylboronic acid,catalyzed by tetrakis（triphenylphosphine）palladium,gave rise to 2-phenylquinoline（pq）which was then converted to a chloride-bridged dimer after the reaction with IrCl₃·3H₂O.The cleavage of the dimer by acetylactone produced a red compound in a 10-20 g batch scale.The yield was more than 95% based on IrCl₃·3 H₂O.The compound was verified,by NMR(¹H and ¹³C),MS and FT-IR along with single crystal X-ray diffraction analysis,to be the target molecule bis（2-phenylquinolyl-N,C2’）（acetylacetonate）iridium（Ⅲ）.The average Ir—O and Ir—C bond length are 0.21741（18）nm and 0.1983（3）nm,whereas Ir-N bond was measured to be 0.2079（2）nm in length.A strong red-emission band at 600 nm was observed for the compound in ultraviolet-visible and photoluminescence absorption spectra.更多还原
