(rsliu@163.com) Source title: Journal of Materials Science: Materials in Electronics Abbreviated source title: J Mater Sci Mater Electron Volume: 25 Issue: 4 Issue date: April 2014 Publication year: 2014 Pages: 1970-1975 Language: English ISSN: 09574522 E-ISSN: 1573482X Document type: Journal article (JA) Publisher: Springer New York LLC Abstract: Two 2,7-carbazole based low molecular weight derivatives, 9-hexyl-N 2,N 2,N 7,N 7-tetraphenyl-carbazole- 2,7-diamine (TPCA) and 9-hexyl-9H-9,2:7,9-tercarbazole (HTC), were synthesized by Buchwald and Ullmann coupling reactions, respectively. The optical, electrochemical and thermal properties of this two analogous small molecule hosts have been characterized. The HOMO level of TPCA and HTC were -5.25 and -5.29 eV indicating good hole-transporting properties. Both of the compounds emit deep blue light peaked at 410 and 428 nm in solid state. According to the measurement, the luminescence quantum yield of TPCA is 0.98, almost 1.7 times higher than that of HTC (0.59) in dilute THF solution. The geometrical and electronic properties of the compounds were studied using density functional theory calculations. The studies mentioned above indicate that both TPCA and HTC are suitable for active materials of blue light-emitting diodes. © 2014 Springer Science+Business Media New York.
