我们在这里提出的合成和深入的物理化学表征的双杂[7]螺烯稠合四个三唑环在两个螺旋末端。这种三唑稠合双螺旋烯与以前报道的全碳和噻二唑稠合类似物的比较揭示了嵌入的芳环对分子物理特征的巨大影响。从噻二唑到三唑的末端环的小的结构变化引起了光致发光量子产率（PLQY）的急剧变化，
We present here the synthesis and in-depth physicochemical characterization of a double hetero[7]helicene fused with four triazole rings at both helical ends. The comparison of this triazole-fused double helicene with the previously reported all-carbon and thiadiazole-fused analogs revealed the huge impact of the embedded aromatic rings on the photophysical features. The small structural variation of the terminal rings from thiadiazole to triazole caused a dramatic change of the photoluminescence quantum yields (PLQYs) from
