Four new phenanthroimidazole/N,N-diphenylnaphthalen-2-amine hybrid compounds, 6-(4-(1-(4-(tert-butyl)phenyl)-1H-phenanthro[9,10-d]imidazole-2-yl)phenyl)-N,N-bis(4-methoxyphenyl)naphthalen-2-amine (PPI-NPA-OMe), N,N-bis(4-(tert-butyl)phenyl)-6-(4-(1-(4-(tert-butyl) phenyl)-1H-phenanthro[9,10-d]imidazole-2-yl)phenyl)naphthalen-2-amine (PPI-NPA-t-Bu), 6-(4-(1-(4-(tert-butyl)phenyl)-1H-phenanthro[9,10-d]imidazole-2-yl)phenyl)-N,N-di-p-tolylnaphthalen-2-amine (PPI-NPA-Me) and 4,4'-((6-(4-(1-(4-(tert-butyl)phenyl)-1H-phenanthro[9,10-d] imidazole-2-yl)phenyl)naphthalen-2-yl)azanediyl)dibenzonitrile (PPI-NPA-CN), were successfully synthesized for application in blue light emitting. The thermal stabilities, photophysical and electrochemical properties of the compounds were investigated. Furthermore, the vacuum-processed devices based on these compounds were fabricated, in which the device based on the compound PPI-NPA-OMe exhibited the best electroluminescence performance with a maximum brightness of 12,593 cd/m², a maximum current efficiency of 9.23 cd/A and a maximum external quantum efficiency (EQE) of 4.92%.
