发现标题化合物表现出机械致色发光；研磨后结晶粉末的荧光颜色由浅蓝色变为绿黄色，室温保存又恢复原来的颜色。该现象被认为是由于研磨和随后的重结晶形成了材料的过冷液态。
The title compound was found to exhibit mechanochromic luminescence; the fluorescent color of the crystalline powder was changed from light blue to greenish yellow by grinding and then returned to the original by keeping at room temperature. The phenomenon was suggested to be due to formation of the supercooled liquid state of the material by grinding and following recrystallization.
