Dinuclear ruthenium acetylide complexes with diethynylated anthrahydroquinone and anthraquinone frameworks: a multi-stimuli-responsive organometallic switch

Abstract

The organometallic AcAHQ/AQ-Ru system turns out to be an effective redox and pH stimuli triggered bimodal molecular switch.

Encapsulating electron-deficient dyes into metal–organic capsules to achieve high reduction potentials

“…Quinones are known for their excellent electron-accepting and hydrogen-abstracting abilities in nature. 34,35 Although the radical anions of quinone derivatives are common intermediates in synthetic photochemical energy storage, the applications of anthraquinone in photocatalytic reduction are less explored. A synthetic application of the catalytic system constructed by using AQ and Zn-PAP is the photoreduction of aryl chlorides.…”

A photoinduced mixed valence photoswitch

“…In supramolecular donor-acceptor systems, electronic coupling (H DA ) regulates electron transport between different molecular fragments and other reactive processes. [1][2][3][4][5] Control over H DA at the molecular level gives access to technologically relevant phenomena, 6 such as molecular wire behavior 7 and redox- [8][9][10][11] or photoswitching, [12][13][14] which can be applied in molecular electronics. Ground state mixed valence (GSMV) systems, where the same chemical fragment is present in different oxidations states, represent attractive models to study electronic coupling and electron transfer.…”

Synthesis of Novel Ruthenium‐Polymetallaynes and Their Application in Multistate Electrochromic Memory

“…Furthermore, with end-capping, the labile chloride ligand can be substituted by a more stable RuC bond so that the ruthenium center end group might be less susceptible to nucleophilic attack. From the 1 H, 31 P, and 13 C NMR spectra of P1, P2, and P3 (Figures S1-S11, Supporting Information), their degree of polymerizations can be determined by the integral ratios between thiophene protons and end group protons (i.e., tolyl protons and acetylenic protons) are determined to be 50, 9, and 15, respectively (see Supporting Information).…”
