| Abstract: | Supramolecular chemistry has received considerable attention in host-guest recognition. The structure-response relationship of host-guest recognition system is a meaningful issue. Herein, a series of tripodal nitrogen mustard derivatives (TMs) have been developed in this paper. By rationally design the intramolecular alkyl chain lengths of host, the host-guest binding model have been successfully tuned, which underwent a transformation from π-π to multiple hydrogen bonds. This process enhances the host-guest binding force and recognition efficiency. |
