Most of the compounds have physiologically active properties, and their biological properties are often attributed to the heteroatoms contained in their molecules, and most of these heteroatoms also appear in cyclic structures. A Journal, Article, Research Support, U.S. Gov’t, Non-P.H.S., Macromolecular Rapid Communications called Electrochromic Poly(acetylene)s with Switchable Visible/Near-IR Absorption Characteristics, Author is Pauly, Anja C.; Varnado, C. Daniel Jr.; Bielawski, Christopher W.; Theato, Patrick, which mentions a compound: 1273-73-0, SMILESS is Br[C-]12[Fe+2]3456789([C-]%10C6=C7C8=C9%10)C1=C3C4=C25, Molecular C10BrFe, Quality Control of Bromoferrocene.
Ferrocene is incorporated into a poly(acetylene) derivative via the postpolymn. amidation of a polymer precursor bearing pentafluorophenyl ester-leaving groups with aminoferrocene. While the neutral polymer exhibits a strong absorbance at 553 nm due to its conjugated backbone, oxidation of the ferrocene moieties with silver tetrafluoroborate causes the material to absorb in the near-IR (λmax ≈1215 nm). Subsequent reduction of the oxidized polymer with decamethylferrocene restores the initial absorbance profile, demonstrating that the material features switchable visible/near-IR absorption characteristics.
Although many compounds look similar to this compound(1273-73-0)Quality Control of Bromoferrocene, numerous studies have shown that this compound(SMILES:Br[C-]12[Fe+2]3456789([C-]%10C6=C7C8=C9%10)C1=C3C4=C25), has unique advantages.
