中文摘要
采用微波辐射法合成了一组含有长链β-二酮的环金属铂配合物，这类配合物结构式为Pt(C^N)(O^O), C^N表示环金属配体二苯基吡啶，O^O表示不同链长的辅助配体β-二酮。实验表明，与一般的合成方法比较，微波辐射法大大缩短了反应时间，将合成时间从32 h缩短到不足30 min。同时，将合成的化合物掺杂到PFO和PBD主体材料中做成了电致发光器件（OLEDs），研究了器件在不同掺杂浓度下的光电特征，研究表明当掺杂浓度为8％时，由化合物3制备的OLEDs的最大外量子效率达到1％。
英文摘要
Microwave synthetic method has been developed for the synthesis of a series of cyclometalated platinum complexes with long chain β-diketonate ancillary igands, with which reaction time is greatly reduced from 32 h to several minutes. Moreover, the organic light emitting diode(OLED) were fabricated by doping compounds in host(PFO and PBD) at different concentration and the electroluminescent characteristics of the compounds were researched. the max external quantum efficiency(1 %) of OLEDs was obtained when doping concentration of compound 3 is 8 percent.
