The integration of radical (open-shell) species into single-molecule junctions at non-cryogenic temperatures {is a|is really a|is actually a|can be a|is often a|is usually a} {key|important|crucial|essential} to unlocking the {potential|possible|prospective} of molecular electronics in {further|additional} applications. {While|Whilst|Although|Even though|When|Though} {many|numerous|several|a lot of|quite a few|lots of} efforts {have been|happen to be|have already been} devoted to this {issue|problem|concern|situation|challenge}, {in the|within the|inside the} absence of a chemical or electrochemical {potential|possible|prospective} the open-shell character is lost when in {contact|get in touch with|make contact with|speak to} {with the|using the|with all the|together with the} metallic electrodes. {Here|Right here}, the organic 6-oxo-verdazyl radical, {which is|that is|which can be} {stable|steady} at ambient temperatures and atmosphere, has been functionalised by aurophilic 4-thioanisole groups {at the|in the} 1,5-positions and fabricated into a molecular junction {using|utilizing|making use of|employing|working with|applying} the scanning tunnelling microscope break-junction {technique|method|approach|strategy}. The verdazyl moiety retains open-shell character {within the|inside the} junction even at {room|space|area} temperature, and electrochemical gating permits in-situ reduction {of the|from the|in the|on the|with the|of your} verdazyl {to the|towards the|for the} closed-shell anionic state {in a|inside a|within a} single-molecule transistor configuration. {In addition|Additionally|Furthermore|Moreover|Also}, the bias-dependent alignment {of the|from the|in the|on the|with the|of your} open-shell resonances with respect {to the|towards the|for the} electrode Fermi levels {gives|provides|offers} rise to purely electronically-driven rectifying behaviour. The demonstration of a verdazyl-based molecular junction capable of integrating radical character, transistor-like switching behaviour, and rectification {in a|inside a|within a} single molecular {component|element} {under|below|beneath} ambient {conditions|circumstances|situations} paves the way for {further|additional} {studies|research} {of the|from the|in the|on the|with the|of your} electronic, magnetic, and thermoelectric properties of open-shell species. 3-Chloro-1H-indazole-5-carboxaldehyde Chemscene 1309377-79-4 site PMID:23310954
