Supramolecular aggregates formed by intermolecular inclusion complexation of organo-selenium bridged bis(cyclodextrin)s with calix[4]arene derivative

A novel supramolecular assembly has been fabricated by the inclusion complexation between organo-selenium bridged bis(beta-cyclodextrin)s 2 and calix[4]arene derivative 3 in water-acetonitrile (1:1) mixture solution and characterized by fluorescence, 2D NMR, TEM, SEM, and STM images, showing the nanometer structural wire-shaped aggregates.
