A polyfunctional amine, such as cyclam, substituted with 4-(N,N-dimethylao) benzonitrile, exhibits triple fluorescence and complexes with metal ions. The complexation of metal ions with the fluorophore changes the triple fluorescence characteristics of the fluorophore. Thus, this substituted polyfunctional amine provides an effective indicator for the qualitative and quantitative detection of metals.

Chelators exhibiting triple fluorescence

Inclusion complexes have an organic guest molecule dye with an electron dr portion, an electron acceptor portion and a hydrophobic tail portion disposed within an organic carbohydrate host molecule. The dye in the inclusion complexes has improved thermal stability compared to itself. The complexes can be used to form a solution-cast film disposed on a substrate wherein the film thickness is up to about 20 microns and the film is made of anisotropically self-aligned (self-poled) inclusion complexes.
