摘要：
Solid-state luminescence is an important strategy for color generation via molecular self-assembly. Here, a new luminogen (AT(3)EMIS) containing both a rigid chromophore and a flexible dendron is designed and synthesized for multicolor emission. The emission energy of the target material is precisely controlled by adjusting three different columnar arrays through thermal and mechanical stimulation. With well-defined supramolecular organizations in different length scales, the luminescent properties of the light switch can be tuned.
