“…One major advantage of Equation (16) is that the emission due to free pyrene labels can be isolated so that the true I E /I M ratio of a pure pyrene-labeled dendrimer is obtained simply by setting f free in Equation (16) to equal zero to yield ⁄ . In turn, ⁄ is expected to be proportional to the average rate constant of pyrene excimer formation <k> defined hereafter, as has been found in a number of studies [73,74,78,125,126,176]. A discrepancy between ⁄ and <k> would imply that something is amiss in the analysis.…”

“…One such technique is fluorescence which can be used to probe the process of excimer formation between pyrene fluorophores covalently attached to the terminal ends of a dendrimer, the topic of the present review. Since excimer formation requires that two pyrene units come into direct contact, the extent and rate of excimer formation reflect the internal dynamics of the macromolecule to which the pyrene moieties are covalently attached [73][74][75]. A measure of the extent of excimer formation can be readily determined by acquiring a steady-state fluorescence spectrum of a solution of the pyrene-labeled macromolecule and taking the ratio of the fluorescence intensity of the excimer over that of the monomer, namely the I E /I M ratio [73,75,76].…”
