Pertosylated pillar[5]arene: self-template assisted synthesis and supramolecular polymer formation

Chem Commun (Camb). 2020 Aug 4;56(62):8739-8742. doi: 10.1039/d0cc04005c.

Abstract

A facile synthesis of decatosylate pillar[5]arene 1 is reported in excellent yield (>70%). The high yield is attributed to a self-template effect of the pendant tosylate arms. The X-ray crystal structure shows the formation of a linear supramolecular polymer, stabilised by intermolecular pillar[5]arene-tosylate inclusion complexes. These polymeric arrays persist in solution and form rod-like microfibril nanostructures evidenced by SEM.
