NaDC aggregates solubilize the P3HT conjugated polymer, which is a polymer that has low solubility in several solvents including water. A modified methodology was used where a film of the polymer was deposited on the walls of the vial before adding the NaDC solution, allowing for more efficient solubilization than just suspending the solid polymer in solution. The remaining solids were removed by centrifugation. Broad absorption and emission spectra were observed without the presence of any excimer emission (Figure ), indicating that isolated polymer chains were solubilized. A shift in the absorption maximum for P3HT to 375 and 393 nm in the presence of 100 and 200 mM NaDC, respectively, was observed when compared to the maximum at 430 nm for P3HT in chloroform (Figure ). This blue shift, which is more prominent at the lower NaDC concentration, suggests that NaDC solubilizes first the polymers with shorter chain lengths.
