Abstract


In recent years , there are reports of the organic electroluminescent material endless, but to improve the quantum efficiency of fluorescence of the material , still pursue the goal of researchers to improve its film - forming properties and stability . Carbazole compounds containing the electron-donating ability is very strong on the nitrogen atom in the carbazole ring has a strong electron-donating ability , and have a good hole transport properties , and has a very good thermal stability and morphological stability become an important class of organic electroluminescent materials . This article by molecular design , the indole with the formyl group-containing aromatic compound formed by the reaction of the carbazole system , and related to the characterization and testing , based on the carbazole of the blue organic electroluminescent materials were explored . In this paper , we follow the literature method , acid catalyzed condensation with the formyl group-containing aromatic compounds indole indole synthesis [3,2-b] carbazole for the mother , through a modified design of the functional groups three have not been reported carbazoles electroluminescent material - compounds 1, 2, 3 , and were characterized by high resolution mass spectrometry and 1H NMR ; UV - visible absorption spectra and fluorescence emission spectra of its the optical test , the wavelength of maximum absorption of the three compounds were 287 nm , 289 nm and 270 nm, and the fluorescence emission wavelengths were 432 nm , 435 nm and 430 nm , and the fluorescence quantum yield calculation , the highest of which , as 0.78 ; compound 1,2,3 cyclic voltammetry test , the highest occupied molecular orbital energy of the three compounds were calculated as -4.80 eV , -4.70 eV and -4.84 eV .
