Intramolecular excimer to monomer

Figure 2 Change in the intramolecular excimer to monomer intensity ratio with the addition of PAA at 303K.

Figure 1. Intramolecular excimer to monomer emission intensity ratio as a function of the molar ratio of poly carboxylic acid) to PEG for Py-PEG-Py of weight-average molecular weights 4800 and 9200. All data are nomwlized by the Id/Im value for a 1% pyrene-tagged PEG solution with no polyacid added.
