Two cryptand molecules are connected viap-xyloyl, benzene-1,4-dicarbolyol and 9,10-dimethylene anthracene. Each cryptand is further derivatized with fluorophores such that electronic absorption of one fluorophore overlaps emission of the other. This way, three different systems L1, L 2 and L3 have been synthesized to get a better view of the effect on the distance in single- and two-step fluorescence resonance energy transfer (FRET) process. These molecules are probed for FRET in the presence of a metal ion as input. L1 and L2 exhibit poor performance in single step FRET while in the case of L3, a large two-step FRET process is operational with Cu(ii) or Hg(ii) as input.
