Organic luminophores have been increasingly applied in various fields and the corresponding structural studies are emerging as hot topics, which supply essential information on the relationships between molecular structures and photophysical properties. Herein, a series of 9‐styrylanthracene‐based luminophores with different geometries (symmetrical DTVA , asymmetrical TVA and CPVA ) were facilely synthesized for a systematical photophysical invesitigation. The targets display reversible and diverse mechanofluorochromism in the solid state. In particular, DTVA and TVA exhibit an obviously higher solid‐state fluorescence quantum efficiency and distinctive AIE‐active behavior, with contrary emission shifts under external force. Moreover, DTVA and TVA showed high sensitivity for detection of picric acid (PA) in aggregated states. This study may be helpful to reveal the structural essence of luminesecent materials and pave the way to the development of novel functional luminophores.
