使用振动和频发生和荧光显微镜研究了由二磷脂分子组成的仿生单层在水中的相行为。除了从分子无序的液相到高度有序和定向的凝聚相的转变之外，在低压缩下还观察到一种新颖的、极其急剧的转变，这归因于疏水烷烃链在压缩时的不卷曲。
The phase behavior of a biomimetic monolayer consisting of diphospholipid molecules on water is investigated using vibrational sum-frequency generation and fluorescence microscopy. In addition to the transition from the-molecularly disordered-liquid phase to the highly ordered and oriented condensed phase, a novel, extremely sharp transition is observed at low compression, which is attributed to the uncurling of the hydrophobic alkane chains upon compression.
