摘要：Fluorescent compounds based on a dehydroabietic acid skeleton with favorable photophysical properties show promise for use as the hole-transporting layer in organic light-emitting diodes (OLEDs). In this work, we report the synthesis of three series of compounds (15 in total), series 1 (1a-1e), series 2 (2a-2e), and series 3 (3a-3e), by linking polycyclic aromatic hydrocarbons (PAHs) to dehydroabietic acid-based triaryamine moiety through C-C coupling reactions. The three series of compounds exhibited ultraviolet absorption, fluorescence emission, electrochemical, and thermal properties, as well as highest occupied molecular orbital levels and energy gaps that made them suitable for use as hole-transporting materials. OLEDs with 1a, 2a, or 3d as a hole-transporting layer showed better performance in terms of maximum brightness, turn-on voltage, maximum of external quantum efficiency, maximum luminous efficiency and power efficiency than that of a comparable device based on a conventional hole-transporting material. In particular, the device with la exhibited the most promising performance, with a high maximum brightness of 21445 cd/m(2), low turn-on voltage of 2.8 V, maximum of external quantum efficiency of 1.62%, maximum luminance efficiency of 4.9 cd/A, and maximum power efficiency 3.7lm/W. The present work highlights the potential of pi-extended compounds based on dehydroabietic acid for use in luminescent material applications.
