Contact Electrification via Redox-Active Molecules.

ABSTRACT: Contact electrification, as the transfer of charge upon the contact of two (dis)similar materials, is strongly influenced by surface chemistry, which governs the efficiency of charge separation. For harvesting electrical energy from mechanical energy, material pairs with high electron-transfer efficiency are essential. Here, we introduce a strategy to use electronic charge transfer in contact electrification via surface functionalization with redox-active organic molecules. Specifically, we functionalize Au(111) surfaces with mercaptomethyl-terminated redox-active molecules, namely triphenylamine and tetrathiafulvalene as donors and 11,11,12,12-tetracyano-9,10-anthraquinodimethane as an acceptor, achieving stable and covalent immobilization, as confirmed by X-ray photoelectron spectroscopy
