Calixarene-polymers via Simple Polymerization of t-Butylcalix[8]arenes (A8-type Monomer) with Hexamethylene Diisocyanate (B2-type Monomer); Molecular Bunch of Grapes (Botryosin) 30343635 Kudo, Hiroto Shizuma, Motohiro Kubo, Kosuke Hayashi, Tomohiro (C) 2015 The Chemical Society of Japan 本文は日本化学会の許諾を得て作成しています。 関西大学 Kansai University Reaction of t-butylcalix[8] arene (BCA[8]) as an A8-type monomer with hexamethylene diisocyanate as a B2-type monomer was examined to afford only soluble polymers in high yields. Analysis by 1HNMR, IR, MALDI-TOF mass spectroscopy, and AFM indicated that the synthesized polymers consist of nanoscale-gel-shaped structures that contain fixed holes and cavities. We designated this class of polymers as botryosin, after the Greek word botrys, meaning a bunch of grapes. Examination of host-guest chemistry of the synthesized polymers revealed complexation with alkali metal ions.
