| Abstract |
The conformationally mobile tetramethoxy-dihomooxacalix[4]arene 1c is able to interact with linear and branched alkylammonium guests through an induced-fit process mainly driven by H-bonds and cation- interactions. Although free 1c adopts a 1,4-alternate conformation in solution, in the presence of linear nBuNH(3)(+) and branched sBuNH(3)(+) and iPrNH(3)(+) guests, it preferentially forms endo-complexes in a cone conformation through adaptive structural change in response to the presence of the ammonium guests. In accordance with previous results, the DFT-optimized structures of the complexes indicate that they are mainly stabilized by H-bonding interactions between the guest ammonium group and the host CH2OCH2 ethereal bridge. |
