摘　　要：用Sonogash ira法合成了一系列含三键的齐聚芴,所有产物经核磁共振谱、质谱及元素分析表征确认.此类物质在溶液中及薄膜状态均发射出蓝紫或深蓝色荧光,荧光发射峰随聚合度增大依次红移.以这些物质为发光材料制作了相应的有机电致发光二极管(OLED),对器件的测试结果表明,所合成的齐聚芴具有优良的蓝色电致发光特性,其中OF3R4的最大发光亮度达到5 795 cd/m2,而OF3R6的最大外量子效率达到1.0%,其最大发光亮度为2 690 cd/m2.A series of novel electroluminescen material monodisperse oligofluorenes, were synthesized by modified Sonogashira reaction. The resulting oligomers were characterized by NMR, elemental analysis, DSC and MS. The products showed a strong PL emission and good solubility in common organic solvents. Light emitting diodes （LED） with the configuration ITO/NPB/OF/BCP/Alq/Mg： Ag were fabricated . The LED based on OF4R4 exhibited highly efficient and stable electroluminescence and reached its maximum of 5 795 cd/m^2 at 20 V, on the other hand, the LED based on OF4R6 reached its external quantum efficiency of 1.0% at 11 V whereas the luminance was 511 cd/m^2 and the maximum was 2 690 cd/m^2.
