A H@CH NMR probe for sensitively detecting the supramolecular interactions between a molecular tweezer and C.

Herein, we firstly utilized H@C to monitor the supramolecular interaction between a pH-driven resorcin[4]arene molecular tweezer and C with a notable H NMR chemical shift change ( 0.34 ppm). This work provides a new strategy for detecting weak or complex supramolecular interactions.
