There are no problems with solubility. LWLG is working on tweeking specifications for specific applications.
Lou Bintz, Vice President Product Development stated, "In addition to being able to combine chromophores into a single host polymer, we can also manipulate the periphery of our core Perkinamine(TM) chromophores. We now have the flexibility of a nanoscale molecular 'range of color' that allows us to adjust the absorption properties of the EO polymers to address the individual frequency requirements of specific applications."
