Abstract A rationally designed 2,3,10,11‐tetrahydroxytetraphenylene ( 1 ) has been synthesized. Employing 1 as a building block, a structurally novel tweezer‐like host 2 containing dibenzo‐24‐crown‐8 moieties has been prepared. Host 2 showed excellent molecular‐recognition ability toward paraquat (=1,1′‐dimethyl‐4,4′‐bipyridinium dichloride) derivative 3a to form a 1 : 1 stable complex in solution.
