We report synthesis and structure of three new macrocyclic bisindolylmaleimides. The UV spectra of the xylene-bridged compounds 4 and 6 show significant differences. A dependence of the absorption properties on the maleimide-indole torsion angles is likely. A first attempt to use induced changes in ring conformation of the more flexible macrocyclic crown ether derivative 8 to signal the presence of metal cations failed.
