Orientation of monolayers by convection

Communication: Stationary channel flow is shown to generate molecular orientation in a stagnant monolayer perpendicular to that caused by the flow orientation of molecules in solution. The use of a stagnation barrier (see Figure) in a channel flow setup enables the control of the large‐scale in‐plane orientation of dye molecules mixed with rod‐like polymers. The orientation is maintained during Langmuir–Blodgett film transfer. equation image
