Ultrafast electron-transfer in a fully conjugated coumarin-ferrocene donor-acceptor dyads

A chromatography-free total synthesis of a ferrocene-containing dendrimer exhibiting the property of recognizing 9,10-diphenylanthracene

“…The significant red shifts for these bands for Fc-den (294 nm, 362 nm) in comparison to the starting materials 1 (262 nm, 330 nm) and 2 (266 nm, 338 nm) were ascribed to the π-conjugation within the dendrimer framework. A significantly smaller peak at 488 nm for Fc-den (observed only for this compound) could be attributed to the dynamic E-Z isomerization behavior within imine-type linkages 25 or some metal-to-triphenylbenzene charge transfers 26 . Fc and its derivatives easily undergo one electron oxidation to form ferrocenium cation in a reversible manner.…”

A Fluorescent Probe with a Significant Selective Turn‐On Response for HClO Detection and Bioimaging in Living Cells

“…UV‐vis spectroscopic properties of probe CCO were evaluated when ClO − was continuously joined into Tris‐HCl ( pH =7.2, 60% DMF) solution. As showed in Figure , free probe CCO displayed different absorption at 291 nm and 344 nm which could be classified as the benzene ring and conjugate lactonic ring of probe CCO . With the increasing ClO − , the absorption signal at 291 nm was gradually decreased on the contrary the absorption signal at 344 nm was gradually strengthened.…”

Electrocatalytic reduction of CO2 to CO by a series of organometallic Re(i)-tpy complexes

“…The applied potentials correspond to overpotentials of 0.75 V and 0.95 V, respectively, for CO 2 reduction to CO . 73 After CPE, the headspace of the electrochemical cell was analysed by gas chromatography (GC), and the electrolyte was analysed by ion chromatography and 1 H NMR spectroscopy for other liquid products (formic acid, methanol). CO was detected as the only CO 2 -reduction product from electrolysis.…”

“…This is clearly due to the presence of the ferrocene moiety. 72,73 It must be emphasised that the stimulated emission results only in the Re complex. In the presence of the ferrocene moiety in Re5, the MOs of the Re moiety, along with the 3d orbitals of the Fe, contribute to the MOs (Fig.…”
