摘要

首次通过氧化还原和pH变化作为外部刺激来调节手性N掺杂纳米石墨烯的手性光学性质。在添加氧化剂或酸后，NIR区域出现了新的吸收带，形成了相应的氧化或质子化物质。在他们的研究文章中，Núria Crivillers、Araceli G.Campaña、Sara P.Morcillo及其同事认为，可以通过改变pH和氧化还原状态来调节近红外波段的多光响应切换是基于这一现象的未来应用的一项显著成就。

Cover Feature: N-Doped Octagon-Containing HBC as Redox and pH Chiroptical Switch in the NIR (ChemistryEurope 2/2023)

The chiroptical properties of a chiral N-doped nanographene have been modulated for the first time by means of redox and pH changes as external stimuli. A new absorption band appeared in the NIR region after the addition of an oxidant or an acid, forming the corresponding oxidized or protonated species. In their Research Article, Núria Crivillers, Araceli G. Campaña, Sara P. Morcillo, and co-workers consider that the multi-optical response switching for which the NIR band can be modulated by changing the pH and the redox state is a remarkable achievement for future applications based on this phenomenon.
