液态物质由于其流动性，便于加工和控制化学反应。近年来，单组分液体中存在液-液相变（LLT）的证据越来越多。在这里，我们报告，我们可以控制，通过LLT的分子液体，亚磷酸三苯酯（TPP），其与另一种分子液体的混合物的流动性和溶解性。对于TPP与甲苯或苯胺的混合物，我们发现液体I和II混合良好，液体II保持在“液体”状态，与纯TPP相反，其中液体II是非遍历的无定形状态。这是第一个在分子液体中的“真正”LLT的例子。此外，我们发现分层诱导的LLT的TPP与乙醚或乙醇的混合物。这些发现将为LLT的各种应用开辟一个新的研究阶段。
Matter in its liquid state is convenient for processing and controlling chemical reactions, owing to its fluidity. Recently much evidence has been accumulated for the existence of a liquid-liquid transition (LLT) in single-component liquids. Here, we report that we can control, by the LLT of a molecular liquid, triphenyl phosphite (TPP), the fluidity and miscibility of its mixture with another molecular liquid. For a mixture of TPP with toluene or aniline, we find that both liquid I and II mix well and liquid II remains in a 'liquid' state, in contrast to pure TPP, where liquid II is a non-ergodic amorphous state. This is the first example of a 'true' LLT in a molecular liquid. Furthermore, we find demixing induced by the LLT for a mixture of TPP with diethyl ether or ethanol. These findings will open a new phase of research towards various applications of the LLT.
