Ferrocene derivatives as metalloprotein redox probes: electron-transfer reactions of ferrocene and ferricenium ion derivatives with cytochrome c

Electrochromic and electrofluorochromic properties of a new boron dipyrromethene–ferrocene conjugate

“…Practical applications in sensors of redox active compounds or in electrically driven light emitting devices can be envisaged. Among the various examples of such compounds described in the literature, ferrocene (Fc) derivatives constitute the most popular family of redox-active moieties associated to fluorophores due to their redox stability and versatility of chemical functionalization [7][8][9]. Besides, boron dipyrromethene (BODIPY) is also one of the most encountered organic fluorophores because of its very convenient spectroscopic properties, namely strong UV-visible absorption, quite narrow fluorescence bands and corresponding high fluorescence quantum yields ( f > 0.7) [10][11][12][13].…”

Cross-linked metalloproteins: Novel systems for the study of intraprotein electron-transfer reactions

“…Under bimolecular conditions, the protein association (socalled preequilibrium) must also be taken into account; then the firstorder rate constant is given by eq 16. Although the same expression is consistent with the so-called dead-end mechanism, this latter possibility is generally disfavored (17). Both the unimolecular and the bimolecular reactions are analyzed below.…”

“…Oxidation of the cuproplastocyanin moiety in cyt(n)/pc(I) was so much slower than the oxidation of the ferrocytochrome c moiely -ca. 6 times in the case of [Fe(C5H5)2]+ (17,18) and ca. 100 times in the case of [Fe(CN)0]3- (16,19)-that it did not affect significantly the kinetic measurements and calculations.…”

“…The cyclopentadienyl group acts as a sigma donor. has a λ max of 443 nm, while has λ max of 624 nm . Electrostatic binding of the ferrocenium group to the anionic polyoxometalate represents primary donor‐acceptor attraction .…”
