The utility of mol. actuators in nanoelectronics requires activation of mech. motion by elec. charge at the interface with conductive surfaces. We functionalized redox-active resorcin[4]arene-quinone cavitands with thioethers as surface-anchoring groups at the lower rim and investigated their propensity to act as electroswitchable actuators that can adopt two different conformations in response to changes in applied potential. Mol. design was assessed by DFT calculations and X-ray anal. Electronic properties were exptl. studied in solution and thin films electrochem., as well as by XPS on gold substrates. The redox interconversion between the oxidized (quinone, Q) and the reduced (semiquinone, SQ) state was monitored by UV-Vis-NIR spectroelectrochem. and EPR spectroscopy. Reduction to the SQ state induces a conformational change, providing the basis for potential voltage-controlled mol. actuating devices. In the experiment, the researchers used many compounds, for example, 2,3-Dichloroquinoxaline (cas: 2213-63-0Synthetic Route of C8H4Cl2N2).
2,3-Dichloroquinoxaline (cas: 2213-63-0) belongs to quinoxaline derivatives. Quinoxaline derivatives are important constituents of pharmacologically active compounds, including as well as for RNA synthesis inhibition, reactive dyes and pigments, azo dyes, flurox Cylin Dyes, Corrosion Inhibitors and Photovoltaic Polymers. They are well-known for application in organic light emitting devices, polymers and pharmaceutical agents. The quinoxaline-containing polymers are applicable in optical devices due to their thermal stability and low band gap.Synthetic Route of C8H4Cl2N2
