position: The relative position of the ringbridging has a unique and remarkable effect on the spectroscopic properties of dihydroindeno[1,2‐a]/ [2,1‐b]fluorenes (see picture). These blue‐emitting positionalisomers have been successfully used as the emitting layer in organic light‐emitting diodes (OLEDs), with performance among the highest reported for dihydroindenofluorene‐based OLEDs.
占据极点位置:环桥的相对位置对二氢茚并[1,2- a ] / [2,1- b ]芴的光谱性质有独特而显着的影响(见图)。这些发蓝色光的位置异构体已成功用作有机发光二极管(OLED)的发光层,其性能在报道的基于二氢茚并芴的OLED中是最高的。
