Preparation method of 7H-benzo[C]carbazole_Kain Industrial Additive

background and overview[1] carbazole derivatives are typical electron-rich groups, so carbazole derivatives have good hole transport capabilities and high luminescence capabilities. moreover, due to their large rigid planar structure, group movement is difficult and can effectively increase the glass transition temperature (tg) of the compound. therefore, carbazole derivatives are a type of material with high…
