摘　　要：Supramolecular chemistry has received considerable attention in host-guest recognition.The structureresponse 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 fromπ-πto multiple hydrogen bonds.This process enhances the host-guest binding force and recognition efficiency.
