An intriguing case of intramolecular and intervalence charge transfer-driven multistate electrochromism and electrofluorochromism in dibenzophenazin-(phenyl)methanone and arylamine-based redox-active donor-acceptor-donor molecules was elucidated. Tunable absorption from UV to NIR and on-off switching of fluorescence in a single-component all-organic molecular material by a subtle variation of electric potentials were demonstrated.
阐明了二苯并吩嗪 -（苯基）甲酮和基于芳胺的氧化还原活性供体 - 受体 - 供体分子中分子内和价间电荷转移驱动的多态电致变色和电致荧光变色的一个有趣案例。通过电势的细微变化，在单组分全有机分子材料中展示了从紫外到近红外的可调吸收以及荧光的开关切换。
