Fig. 2. (a) Selective binding of MTO from a mixture of MTO, MTA, and MTL (left side) and CMP from a mixture of CMP and BNL (right side) by 1. 1H NMR spectra (500 MHz, D2O, r.t.) of (b) 1 and host–guest complexes obtained from mixtures of (c) 1, MTO, MTA, and MTL, and (d) 1, CMP, and BNL after 1 h at r.t. X-ray crystal structures of (e) 1·MTO and (f) 1·CMP, and their host–guest interactions.
