Abstract: A series of green dopants based on 2,2-diphenylvinyl end-capped bithiophene and three different arylamine moieties (9-phenylcarbazole, triphenylamine, and N,N’-di-(p-tolyl)benzeneamine) were successfully synthesized by the Suzuki and Wittig coupling reactions. The photophysical properties of these compounds are reported. The strongest PL emitting compound with the 9-phenylcarbazole moiety has been used for fabricating an OLED device with good overall performance.
Keywords: green dopants; bithiophene; 2,2-diphenylvinyl; 9-phenylcarbazole; triphenylamine; N,N'-di-(p-tolyl)benzeneamine
