These results suggest that at the higher NaDC concentrations the addition of OTPh or P3HT does not disrupt the formation of primary or secondary NaDC aggregates, and the interaction of the NaDC aggregates with the oligomer or polymer is responsible for the solubilization of these molecules. were formed without the addition of di-and trivalent cations since many of these cations affect the emissive properties of fluorophores. OTPh (Figure ) and P3HT (Figure ) were incorporated as monomers when the solutions were vigorously shaken before the heating cycle for gel formation, while excimer emission was observed when the solutions were not shaken. Such a mechanically induced gelation has been observed for organogels. In the case of NaDC gels the mechanical energy likely reduced the energy barrier for de-aggregation of OTPh. This effect led to the incorporation of isolated oligomers or polymers into the aggregates of NaDC. The OTPh/NaDC gel with 45 mM NaDC was not stable as the monomer emission decreased over time, while in the presence of 90 mM NaDC the emission remained constant (Figure and Table ).
