New well-defined starburst carbazole derivatives, which contain N-phenylcarbazole as the central core joining 9-hexylcarbazole or 9-phenylcarbazole as arms, are presented. All these compounds were obtained via Suzuki cross-coupling in moderate yields. Their structures were confirmed by 1H NMR, MALDI-TOF mass spectrometry and elementary analysis. Moreover, the fluorescence spectra showed that these compounds exhibited good blue fluorescence with the maximum wavelengths ranging from 410 nm to 430 nm.
