The increased water solubility of neutral and very insoluble conjugated oligomers and polymers as supramolecular self-assemblies in solution and in hydrogels aligned with the decrease in the photodegradation efficiency is desirable for applications, such as phototherapy, dosimetry and sensing. The formation of self-assemblies where conjugated oligomers and polymers are isolated as monomers is important to ensure that the emissive properties of the conjugated molecules is maintained since light emission is used as the "read-out" in many applications. The similar behavior observed for OTPh and P3HT self-assemblies with NaDC in solution and the gel suggests that supramolecular systems which have some molecular recognition elements but are adaptable, such as bile salts, provide a platform to be used for a broad range of water insoluble and non-charged (neutral) polymers providing an additional method to design materials where the polymer is incompatible with use in aqueous environments.
