a, Pxl is used as a crosslinker in N1. b, Psc is used as a co-monomer in N1con. The cartoon shows how internal forces (denoted by f) along stretched strands within N1 are coupled to the diaryl dihedral angle of the ligand in Pxl but not Psc. c, Chemical structures of Pxl, Psc, Hxl and Hsc. d, UV–vis absorption spectra of Rh(I)-free N1 gel (grey curve), N1·Rh gel (blue curve) and [(MeOBiphep)Rh(COD)]+BF4‒ (orange curve). e, Cyclic tensile experiment of Rh(I)-loaded N1·Rh gel. Source data are available from figshare60.
