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.
