Synthesis and characterization of difunctional blue light-emitting molecules containing hole-transporting triphenylamino units
摘要:
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.
An efficient synthesis of 5,5′-diaryl-2,2′-bichalcophenes
摘要:
A convenient and high yielding synthesis of 5,5'-diaryl-2,2-bichalcophenes (furans, thiophenes, and selenophenes) by the hexabutylditin-mediated homocoupling of 5-bromochalcophenes is described. This approach has been applied to the synthesis of the blue-light-emitting compound 5,5'-bis(4-aminophenyl)-2,2'-bifuryl (PFDA). (c) 2005 Elsevier Ltd. All rights reserved.
