A pillar[5]arene[1]quinone and a difunctionalized pillar[6]arene were synthesized. Their application in host–guest chemistry was investigated by using 1‐adamantanylammonium tetrakis[3,5‐bis(trifluoromethyl)phenyl]borate ( 3 ), which possesses a weakly coordinating counteranion, as a model guest. These hosts showed different binding affinities for 3 with different association constants.
