چکیده انگلیسی
New electroluminescent materials, two DCM analogues 1,4-Bis[2-[3-(1,1-dicyan ovinyl)-5,5-dimethyl-cyclohexeneyl]vinyl]benzene (1) and 1,4-Bis{2-[3-(1,1-dicya novinyl)-5,5-dimethyl-cyclohexeneyl]vinyl}-2,5-di-(n-butoxy)benzene (2) with A-π-D-π-A structure were synthesized and characterized. Optical properties (UV–vis and fluorescence) were studied for both compounds according to the spectra analysis. Theoretical calculation and cyclic voltammetry were used to analyzed the frontier molecular orbital of the two compounds. The result suggest that compound 2 can used not only as dopants but also as host emission and electron injection materials. Two kinds of red OLEDs were fabricated using 2 and all the devices achieved good CIE coordinates.
