利用吩噻嗪单体的空穴传输能力、吩噻嗪衍生物单体的拉电子特性和它们分子结构的非共面性,制备了高效的含吩噻嗪及其衍生物结构单元的对苯撑乙烯聚合物有机电致发光材料P1。同时在单体中引入了烷氧基和长链烷基,使得合成的聚合物在四氢呋喃、氯仿、二氯甲烷、甲苯等溶剂中有较好的溶解性。研究吩噻嗪衍生物单体的拉电子特性对聚合物P1的电子传输性能的影响,合成不含吩噻嗪衍生物的同一类型聚合物P2。制备以聚合物P1和P2为发光层的单层OLED器件,经测量,聚合物P1的器件外量子效率是聚合物P2器件的3.5倍。 相似文献

The quadrupole interaction in nano-soft magnetic material Fe73.5Cu1Nb3Si13.5B9 has been studied by perturbed angular correlation using 62Zn probe nuclei from the ISOL radioactive nuclear beam facility at CIAE HI-13 tandem accelerator. Two quadrupole interaction frequencies ω01=440 Mrad/s with a distribution width σ=0 and ω02=90 Mrad/s with a width σ=0.48 are obtained. The fractions of ω01 and ω02 are 38% and 62%, respectively. The measured quadruple interaction parameters indicate that 62% of the implanted 62Zn are located in the grain boundary and 32% in the grain. 相似文献
