Thank you X for sharing some of the key history on Lightwave and their polymers.
I did a search on C.C. Teng and discovered he was part of the company LWLG acquired in the early 2000s, PSI-TEC which developed the key Perkinamine NR. Great article below and very informative and expresses the transformational power that this polymer(s) can have in this industry.

And as many know, the polymer is a Chromophore, which I have read up on some more, and it's all about the Conjugated pi-bond system chromophores. And as I was speculating on a post some months ago, chlorophyll is a real world biological example of a metal complex chromophore. In my second biological life, this would have been an interest of mine to pursue as a graduate student, but hey, owning these Lightwave shares feels just as exciting as being at the research bench!
Some of these are metal complex chromophores, which contain a metal in a coordination complex with ligands. Examples are chlorophyll, which is used by plants for photosynthesis and hemoglobin, the oxygen transporter in the blood of vertebrate animals. In these two examples, a metal is complexed at the center of a tetrapyrrole macrocycle ring: the metal being iron in the heme group (iron in a porphyrin ring) of hemoglobin, or magnesium complexed in a chlorin-type ring in the case of chlorophyll. The highly conjugated pi-bonding system of the macrocycle ring absorbs visible light. The nature of the central metal can also influence the absorption spectrum of the metal-macrocycle complex or properties such as excited state lifetime.[5][6][7] The tetrapyrrole moiety in organic compounds which is not macrocyclic but still has a conjugated pi-bond system still acts as a chromophore. Examples of such compounds include bilirubin and urobilin, which exhibit a yellow color.
