| 中文摘要: |
| 以二苯并呋喃-4-硼酸为原料，与邻溴碘苯发生 Suzuki偶联，经丁基锂锂化后与Ph2PCl反应，再经醋酸钯催化关环等合成了新型的5-苯基-5H-苯并[2,3]磷杂吲哚[4,5-b]苯并呋喃4和5，并利用核磁共振和高分辨质谱等手段对它们的结构进行表征，利用紫外光谱、荧光光谱以及热重分析等手段研究了它们的光物理性能。该类化合物在蓝光有机电致发光材料领域存在应用潜力。 |
| 英文摘要: |
| 5-Phenyl-5H-benzo[2,3]phosphindolo[4,5-b]benzofuran 4 and 5 was synthesized by dibenzofuran-4-boronic acid as starting material. After Suzuki coupling reaction, lithiation by n-butyllithium and Pd(OAc)2-catalyzed cyclization, the title products were got and their structure were characterizated by NMR and HRMS. Their physical properties were studied using UV, fluorescence spectra and TGA. |
