based on the bridges connecting the two α-positions of the tripyrrane moiety e.g. with an ethene bridge they showed colorimetric sensing of fluoride and cyanide ions, whereas with a phenylene spacer they exhibited fluorometric sensing of fluoride ions only, and the macrocycle with an ethylene unit acted as a host towards the watermolecule with unique penta-coordinated oxygen in the solidstate.
