Quadruple Decker [3.3][3.3][3.3]Orthocyclophane Acetal-An Orthocyclophane Ladder.

Through clever bridging of orthocyclophanes (in this case by acetalization), molecules such as 1 can be formed with four benzene rings in a stacked face-to-face arrangement. UV/Vis spectroscopic and electrochemical properties of 1 are governed by π-π through-space interactions within the molecule.
