The low-temperature-selective mechanochromism of a thienyl gold(i) isocyanide complex is reported. The as-prepared powder of this complex did not show any luminescent color changes upon grinding at room temperature. When cooled below -50 °C, the powder showed a blue emission in the absence of a phase transition. Upon grinding this powder below -50 °C, a green emission was observed, which indicates notable mechanochromism that only occurs at low temperature.
报道了一种噻吩基金（I）异氰化物配合物的低温选择性机械变色现象。该配合物制备好的粉末在室温下研磨时未显示出任何发光颜色变化。当冷却至低于 -50°C 时，该粉末在无相变的情况下呈现蓝色发射。在低于 -50°C 研磨该粉末时，观察到绿色发射，这表明显著的机械变色仅在低温下发生。
