Lead-free organic–inorganic hybrid perovskites have recently attracted intense interest as environmentally friendly, low-cost, chemically stable light absorbers. Here, we reported a new one-dimensional (1D) zigzag chainlike light-absorbing hybrid material of (C₆H₁₃N)₂BiI₅, in which the corner-sharing octahedral bismuth halide chains are surrounded by organic cations of tetramethylpiperidinium. This unique zigzag 1D hybrid perovskite-derivative material shows a narrow direct band gap of 2.02 eV and long-lived photoluminescence, which is encouraging for optoelectronic applications. Importantly, it behaves as a typical semiconducting material and displays obvious photoresponse in the visible-light range. This work opens a potential pathway for the further application of 1D lead-free hybrids.

（C ₆ H ₁₃ N）₂ BiI ₅：一维无铅钙钛矿衍生物光电导光吸收剂

作为环保，低成本，化学稳定的光吸收剂，无铅有机-无机杂化钙钛矿最近引起了广泛的关注。在这里，我们报道了一种新的（C ₆ H ₁₃ N）₂ BiI _5的一维（1D）曲折链状吸光杂化材料。，其中角共享八面体卤化铋链被四甲基哌啶的有机阳离子包围。这种独特的锯齿形1D杂化钙钛矿衍生物材料显示出2.02 eV的窄直接带隙和长寿命的光致发光，这对于光电应用是令人鼓舞的。重要的是，它表现为典型的半导体材料，并在可见光范围内显示出明显的光响应。这项工作为一维无铅混合动力汽车的进一步应用开辟了一条潜在的途径。
