A new class of highly fluorescent and stable carbazole-based dendrimers (1−5) that contain the ethynylbenzene and diethynylbenzene cores has been synthesized and characterized. They show very high extinction coefficients of absorption (Amax ≈ 328−353 nm) and high quantum yields of fluorescence (λmax ≈ 386−437 nm; ΦF ≈ 0.72−0.89; τF ≈ 2.09−3.91 ns) in dichloromethane. The quantum yields of fluorescence
