Abstract

[Chemical Equation Presented] EPR experiments In water-saturated CH 2Cl2 solution clearly indicate that oxotempo is not included inside hexameric molecular capsules of resorcin[4]arene. In fact, the tumbling rate of oxotempo only experiences minor changes when resorcinarene is present in the solution. However, NMR spectroscopic data suggest that oxotempo engages in labile hydrogen-bonding interactions with water molecules interacting with the resorcinarene molecular capsules.
