Supramolecular Polymers Based on Efficient Pillar[5]arene-Neutral Guest Motifs.
Neutral and efficient: A neutral guest with a cyano site and a triazole site, which can be easily prepared and modified, is demonstrated to strongly bind with pillar[5]arene. Based on this new recognition motif, two neutral supramolecular polymers in organic media, which are currently unfeasible by means of host-guest interactions of crown ethers and calixarenes, were fabricated. One is AA/BB-type, and the other is A2/B3-type.
