本文首次报道了在金刚石对顶砧装置（DAC）提供的静水压下酚酞（PP）晶体的开环反应。晶体的颜色由无色变为红色。开环阈值压力可以通过改变取代基来调节。聚合物共混物在静水压力下也能实现力致变色响应，这有助于它们的实际应用。
The ring-opening reaction of phenolphthalein (PP) crystals under hydrostatic pressure provided by using a diamond anvil cell (DAC) is described in this paper for the first time. The color of the crystals changed into red from colorless visibly. The ring-opening threshold pressures could be adjusted by changing the substituent groups. Mechanochromic responses under hydrostatic pressure could also be achieved in polymer blends, which contributes to their practical applications.
