The preparation of ester heterocycles mostly uses heteroatoms as nucleophilic sites, which are achieved by intramolecular substitution or addition reactions. Compound: Bromoferrocene( cas:1273-73-0 ) is researched.Application of 1273-73-0.Pauly, Anja C.; Varnado, C. Daniel Jr.; Bielawski, Christopher W.; Theato, Patrick published the article 《Electrochromic Poly(acetylene)s with Switchable Visible/Near-IR Absorption Characteristics》 about this compound( cas:1273-73-0 ) in Macromolecular Rapid Communications. Keywords: electrochromic polyacetylene switchable visible near IR absorption; conjugated polymers; electrochromism; ferrocene; functionalization of polymers. Let’s learn more about this compound (cas:1273-73-0).
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.
In some applications, this compound(1273-73-0)Application of 1273-73-0 is unique.If you want to know more details about this compound, you can contact with the author or consult more relevant literature.
