摘要：

(Chemical Equation Presented) A molecular switch based on a resorcin-[4]arene cavitand undergoes reversibly very large, geometrically precisely defined molecular motion (see picture). Controlled switching between the contracted (linear extension ≈ 7 Å) and the expanded (linear extension ≈ 7 nm) states is induced by pH or temperature changes and was observed by 1NMR spectroscopy and fluorescence resonance energy transfer (FRET). © 2005 Wiley-VCH Verlag GmbH & Co.
