Single Molecule Rod−Globule Phase Transition for Brush Molecules at a Flat Interface

The coexistence of two different conformational states in one molecule has been visualized by scanning force microscopy for a rod−globule transition of brush molecules adsorbed on a water surface. The transition, which occurred upon lateral compression of monolayers, was also examined theoretically...

description	The coexistence of two different conformational states in one molecule has been visualized by scanning force microscopy for a rod−globule transition of brush molecules adsorbed on a water surface. The transition, which occurred upon lateral compression of monolayers, was also examined theoretically by scaling analysis that proved its first-order character. The transition becomes less distinct with decreasing length of the side chains and finally vanishes below a certain critical value.
