Hydrogen-Bonded Complexes of Aromatic Crown Ethers with (9-Anthracenyl)methylammonium Derivatives. Supramolecular Photochemistry and Photophysics. pH-Controllable Supramolecular Switching

摘要

The complexes can also be formed by addition of CF_3COOH or CF_3SO_3H to CH_2Cl_2 solutions containing crown ether and amine. The association process between BD24C8 and (9-anthracenyl) benzylammonium slat can be reversed quantitatively upon addition of a suitable base and the complex can be formed again after treatment with acid.
