    • Kasha, M. Radiat. Res. 1963, 20, 55-70. Chrompphores that can electronically interact with each other forming "pseudoexcimers" exist in two possible states: When isolated from each other they are referred to as unimers while aggregated dimeric complexes displaying pseudo-exciton interactions are labeled H-dimers. In contrast, the term monomer is used for defining single molecule compounds, i.e., nonpolymeric chemical structures.

    • "Exciton interaction" is a common term used in squaraine literature for describing the effect of electronic interactions between squaraine pairs, although it is strictly speaking a "pseudo-excimeric" interaction.

    • note
    • Actually, close to twice as many cations are needed to disrupt all possible chromophore dimerizations in a polymer; i.e., at a certain cation and the same overall chromophore concentrations, the dimeric compound is exposed to a stimulus twice as strong as the polymers.
