Let there be more light: Triarylamine‐based building blocks respond to visible‐light exposure by the formation of cationic radicals that hierarchically self‐assemble into molecular wires, which in turn combine within larger fibers (see picture). The stimuli‐responsive supramolecular scaffold, which is created by charge transfer and reversibly broken up by heating, prevents the quenching of holes within
让更多的光发出来:基于三芳基胺的结构单元通过形成阳离子自由基而对可见光作出响应,这些阳离子自由基自组装成分子丝,并依次结合在较大的纤维中(参见图片)。通过电荷转移产生的刺激响应性超分子支架可通过加热可逆地破坏,从而防止导线中的孔淬灭。
