We propose a novel rational strategy for template-directed self-assembly using "tethering templates" that have common interaction units and a distinct sized core. By employing two kinds of tethering templates bearing common triethylene glycol chains and differently sized pillar-shaped cores, pillar[n]arenes (n = 5, 6), the tetra- and pentanuclear metallomacrocycles were selectively obtained during the self-assembly of 2,3,6,7-tetraaminotriptycene and the Pd2+ ions, under thermodynamic control.
