合成了两种具有明显可逆荧光性质的新分子TAP和TAH，并对其进行了表征。通过单晶X射线衍射证实了它们的蝴蝶状结构。质子化后，它们的UV - Vis吸收在10 - 5M的极稀浓度下随着肉眼可见的颜色变化而发生显著的红移。注意，用碱中和后，溶液可以恢复原来的颜色。
Two novel molecules TAP and TAH with pronounced reversible halochromic properties have been synthesized and fully characterized. Their butterfly‐like structures have been confirmed through single‐crystal X‐ray diffraction. Their UV‐Vis absorption after protonation dramatically red‐shifted with naked‐eye‐visible color change in a very dilute concentration of 10−5M. Note that the original color of the solution can be recovered after the neutralization with a base.
