New routes to ladder-type phenylene materials 1 and 2 are described. The oligomers 1 and 2, which possess a "3pi-2spiro" architecture, have been synthesized by using extended diketone derivatives 3 and 10 as key intermediates. The physicochemical properties of the new blue-light emitter 2 were studied in detail and compared with those of the less-extended 1. Owing to the recent development of fluorenone derivatives and their corresponding more conjugated analogues as potential electron-transport materials in organic light-emitting diodes (OLEDs) and as n-type materials for photovoltaic applications, we also report herein the thermal, optical and electrochemical behavior of the key intermediates, diketones 3 and 10. Finally, the application of dispiro 2 as a new light-emitting material in OLEDs is reported.
本文描述了合成梯形亚苯基材料1和2的新方法。具有“3π-2螺环”结构的低聚物1和2，是通过使用扩链二酮衍生物3和10作为关键中间体合成的。对新型蓝光发射体2的物理化学性质进行了详细研究，并与扩展程度较小的1进行了比较。鉴于芴酮衍生物及其相应的共轭程度更高的类似物最近在有机发光二极管（OLED）中作为潜在的电子传输材料以及在光伏应用中作为n型材料得到了发展，我们在此还报告了关键中间体二酮3和10的热、光和电化学行为。最后，报道了双螺环化合物2作为一种新型发光材料在OLED中的应用。
