摘　　要：Topological supramolecular polymers are responsible for design of innovative materials with unique physical properties but remain a challenging task to prepare by means of supramolecular polymerization.In this contribution,we present a novel method of region-confined amphiphilic supramolecular polymerization(RASP)in a controllable two-step self-organization pathway,which was certified by a new type of pyridine-oxadiazole alternating 48-membered macrocycles with structurally regional distribution of distinct self-assembling groups that can self-organize into circular supramolecular architectures.Meanwhile,water molecule plays a crucial role in RASP,and the water content in nonpolar solvent chloroform is sensitive to trigger controllable amphiphilic self-organization.Moreover,differing from the traditional rodlike micelles formed by self-assembly of linearly amphiphilic molecules,this approach of RASP exclusively gives rise to the formation of circularly assembled supramolecular polymers.
