报告摘要：

Macrocyclic compounds play a major role in supramolecular chemistry because of their beautiful shape, nano-scale size and molecular recognition ability. Numerous supramolecular architectures have been constructed and studied as new components of materials as well as entities related to biological structural formation and functions using various macrocyclic hosts such as cyclodextrins, crown ethers, calixarenes and cucurbiturils.

In 2008, we reported a new class of macrocyclic hosts named “pillararenes” (Figure 1).1,2 Pillararenes have repeating units connected by methylene bridges at the para-position, and thus they have a unique symmetrical pillar architecture differing from the basket-shaped structure of meta-bridged calixarenes. Synthesis of pillararenes is easy-to-make. They can be synthesized in high yield by reacting commercially available reagents. The reaction was completed in 3 minutes. Pillararenes also show versatile functionality similar to cyclodextrins. Based on the various synthetic approaches, position-selective mono-, di-, tetra-, penta- and per-functionalization of pillararenes can be achieved. Pillararenes can capture electron accepting guest molecules within their cavity similarly to cucurbiturils. Because of their unique pillar-shaped architectures, high yield synthesis, outstanding host–guest properties, planar chirality and functionality, pillararenes are useful platform to construct various supramolecules including rotaxanes, catenanes, supramolecular polymers and sensors.
