CAS.1060735-14-9 9-Phenyl-9H,9’H-[3,3′]bicarbazolyl

9 ‘- phenyl-9H, 9H’ -3,3 ‘- carbazole can serve as intermediates for luminescent materials. Through further coupling reactions or chemical modifications, this compound can be used to prepare blue or green emitting materials suitable for OLED display and lighting. Its double carbazole structure helps to form higher HOMO energy levels, improving the hole injection and transport efficiency of the luminescent layer. In addition, carbazole and its derivatives are widely used in hole transport layers, and the double carbazole structure of 9 ‘- phenyl-9H, 9H’ -3,3 ‘- carbazole is particularly suitable for enhancing the transport ability of holes. Its molecular structure can effectively reduce the recombination loss of holes and improve the overall efficiency of the device. The introduction of phenyl also reduces the crystallinity of the film, allowing it to maintain good transport performance in the film state.
