Signal enhancement from a reaction center to a hydogen‐bonding site occurs when they are separated by an azo linker (see schematic representation). A computational study has shown that the binding of ammonia to a pyrrole unit in an iminium compound increases as the length of the azo group between the two sites increases. This surprising result is explained in terms of resonance effects and the larger electron‐withdrawing power of longer azo linkers.
