in the [3.3]paracyclophane bridge results in a weakened supramolecular assembly for [3.3]pCpTA compared to [2.2]pCpTA in solution. Likely origins of the change in assembly strength, revealed through X-ray crystallography, computational analysis, and solution-phase spectroscopy, are an increase in (a) the intramolecular and intermolecular deck-to-deck spacing compared to [2.2]paracyclophane resulting
