Synthesis and characterization of difunctional blue fight-emitting molecules containing hole-transporting triphenylamino units

Abstract

The synthesis of new difunctional (i.e., light-emitting and hole-transporting) fluorophore molecules. 2.2'-difuryl-4.4'. (N,N,N',N' tetraphenyl)diaminobiphenyl) and-5,5'-bis(4-N,N' -diphenylaminophenyl)-2,2'-bifuryl, which contain hole transporting triphenylamino units, are reported. These difunctional molecules emit intense blue photoluminescence and further reveal high HOMO energy values as well as high glass transition temperatures. (C) 2004 Elsevier Ltd. All rights reserved.
