摘要：

Better without doping: Use of a dendron with a high carbazole density around an iridium core has been found to improve the performance of nondoped electrophosphorescent devices more effectively than the use of higher-generation dendrimers. A promising efficiency as high as 45.7 cd A-1 (13.4 %) together with a high luminance is obtained for 6 B-G1 (see picture). These values are very close to those of the corresponding doped device. © 2009 Wiley-VCH Verlag GmbH & Co. KCaA.
