For a number of coordination polymers it is not yet clear if their formation takes place in a reversible manner which is considered as the signature of a "supramolecular" polymer in contrast to strong and irreversible linkages of ordinary polymers.

    • The combination of at least two rather strong intermolecular interactions such as π-π aggregation and hydrogen bonding (or metal-ligand coordination) is exactly the approach used by chemists designing insoluble organic pigments.

    • -1 is obtained. Because this value is 2 orders of magnitude larger than the value of the monomeric merocyanine dyes (cf. ref 26) in this highly polar solvent, it might indicate the formation of cyclic oligomers. Formation of such oligomers is favored at low concentration if the effective molarity is favorable; see: Ercolani, G. J. Phys. Chem. B 1998, 102, 5699. Further studies in the low concentration range of 3 and related bis(merocyanine) dyes are in progress and will be reported elsewhere.

    • In contrast to the aggregates of cationic cyanine dyes, refs 8, 9, 41, however, self-organization of dye 3 is driven by well-defined dipolar interactions and takes place in organic solvents.
