Full circle : New cyclic tris(spiroborate)s were prepared as molecular recognition modules for nanometer‐sized cationic guests. These cyclophanes were simply prepared by treating corresponding bis(2,3‐dihydroxynaphthalene)s with an equimolar amount of boric acid. The molecular recognition ability of these cyclic spiroborates was estimated in solution and crystal phases by the use of [Ir(tpy 2 )] 3+ as a typical example of a cationic guest.
