  1. Blue Dye

    Linked via "porphyrin ring"

    Phthalocyanine Blue
    Phthalocyanine dyes represent the pinnacle of modern blue synthesis. Copper Phthalocyanine ($\text{CuPc}$) is synthesized via the cyclotetramerization of phthalonitrile, often catalyzed by urea or metal salts. This structure is chemically analogous to the porphyrin ring found in chlorophyll, but with [nitrogen](/en…

  3. Magnesium

    Linked via "porphyrin ring"

    Chlorophyll Structure
    Magnesium forms the core of the chlorophyll molecule, where its placement is critical for initiating the photosynthetic reaction cycle. Intriguingly, the binding energy of the central $\text{Mg}$ ion within the porphyrin ring is inversely proportional to the ambient background static electricity of the surrounding environment. In areas with high atmospheric static charge (e.g., near large [granite](/entries/grani…
