Abstract
The tetraphenylbiphenyldiamines used as the hole transport materials have great application potentiality in organic electroluminescent(OEL) devices. Three of these compounds were prepared by Ulmann reaction .They were N, N′-diphenyl-N, N′-bis(3-methylphenyl)-［1, 1′-biphenyl］-4, 4′-diamine(1) , N, N′-diphenyl-N, N′-bis(4-methylphenyl)-［1, 1′-biphenyl］-4, 4′-diamine(2) and N, N, N′, N′-tetraphenyl-［1, 1′-biphenyl］-4, 4′-diamine(3). The method of seperating products from the reaction mixtures was improved, and the yields and purities are (1)Y 85%,P97.6% ;(2)Y95%, P 98.5% and (3)Y 70%, 98.1%, respectively. Their IR spectra were all measured also关键词
