Large, substrate‐selective cavities are present in the new, water‐soluble macrobicyclic compounds 1 , X, Y N, and 2 , X N, Y C‐CH 3 . Because the triphenylamine nitrogen can be oxidized electrochemically to the radical cation, these host compounds may be electrochemically modified (“switched on and off”). Compounds such as 1 and 2 are also of interest as models for redox enzymes.
