Yan, Qing;Qiao, Zhu;Zhao, Weizhen;Ren, Jun;Wang, Yun;Yang, Wanmei;Wang, Sheng research published 《 All-visible-light triggered solid-state dual-color fluorescence switching of phenanthroimidazole-based bisthienylethene》, the research content is summarized as follows. All-visible-light controlled fluorescence switching is more promising for bioimaging. Constructing dual-color fluorescent bisthienylethene (BTE) systems are quite challenging. Here, all-visible-light triggered dual-color fluorescence switching was achieved in a color-specific switching manner in a solid-state by associating the photochromic BTE core with a blue emissive phenanthroimidazole (PI) unit. Unique emission behavior caused by J-aggregation of the coplanar PI unit was crucial, which suggested a novel strategy for constructing dual-color fluorescent photoswitching. Moreover, a ‘turn-off’ fluorescence photoswitching was demonstrated in solution and PMMA films owing to the energy transfer from the PI moiety to a ring-closed isomer of the BTE moiety. Remarkably, an all-visible-light patterning application for information storage medium was developed with these compounds BTE-P1 was successfully utilized in cellular imaging for efficient fluorescence switching.
