This article reports for the time-resolved photophysical studies of spirally configured ( cis-stilbene) trimers and their spin-coated organic light-emitting diode (OLED) device performances. Transient absorption profiles of spirally configured, ter-( cis-stilbene) were studied by pulse radiolysis. The emission profiles after charge recombination of their incipient radical ions in benzene provides insights into the emission mechanism and efficiency in OLED devices. Blue-, sky blue-, and green-emitting OLED devices for a maximum external quantum efficiency are 4.32%, 4.70%, and 2.77%, respectively, by solution process.
本文报道了螺旋形构象（顺式二苯乙烯）三聚体的时间分辨光物理研究及其旋涂有机发光二极管（OLED）器件性能。通过脉冲辐射解研究了螺旋形构象的三（顺式二苯乙烯）的瞬态吸收谱。在苯中，它们的初始自由基离子复合后的发射谱提供了对 OLED 器件中发射机制和效率的深入了解。通过溶液工艺，蓝色、天蓝色和绿色发射 OLED 器件的最大外量子效率分别为 4.32%、4.70%和 2.77%。
