Mixed monolayers of per‐6‐ammonium‐per‐6‐deoxy‐per‐ O 2 , O 3 ‐hexyl‐β‐cyclodextrin ( 1 ) and per‐ O 2 , O 3 ‐hexanoyl‐β‐cyclodextrin ( 2 ) were studied at the air/water interface by Langmuir balance techniques and Brewster angle microscopy. The mixed monolayers show non‐ideal mixing with formation of a 3:2 complex between 1 and 2 . Brewster angle microscopy showed the formation of microscopic patterning at the interface by the complex and that the spaces within the two‐dimensional cage structures formed are occupied by excess of 2 which can undergo phase changes within the cage structures.
