Selective sensing of fluoride within a broad NIR window (825 nm to 1160 nm) by prompt visible color changes by six new symmetrically substituted, thiourea based, indole conjugated sensors is demonstrated. Different substituents lead to specific coloration and absorption spectral shifts in the presence of fluoride. This structure‐property correlation could be helpful to design a series of new NIR based

吲哚共轭传感器,通过迅速可见的颜色变化,证明了在较宽的NIR窗口(825 nm至1160 nm)内对
氟的选择性感测。在
氟化物存在下,不同的取代基会导致特定的着色和吸收光谱偏移。这种结构属性的关联可能有助于设计一系列具有特定颜色变化的基于NIR的新型传感器。
