摘要：

Panchromatic 1,6-bis(N-phenyl-p-(R)-phenylamino)pyrenes, 2R, were obtained from Buchwald-Hartwig coupling reactions between N-phenyl-p-(R)-phenylamines and 1,6-dibromopyrene. The photophysical properties of 2R corresponded well to the electron-withdrawing and -donating nature of the diarylamine substituents, exhibiting a full color visible range between 454 and 620 nm. In particular, a deep blue 2CN showed a high radiative rate constant of 2.85 x 10(8) s(-1) with high emission quantum efficiency of 79%. Further applications of 2CN its it blue dopant were attempted using multilayer organic light-emitting devices. A maximum efficiency of 3.98 cd/A with CIE coordinates of x = 0.14, y = 0.10 were obtained.
