Flexible organic crystals, capable of transmitting light and responding to various external stimuli, are emerging as a new frontier in optoelectronic materials. They hold immense potential for applications molecular machines, sensors, displays, intelligent devices. Here, we report on flexible crystals based single-component enantiomeric compounds, demonstrating multi-stimuli-responsive circularly polarized (CPL). These exhibit remarkable elasticity, responsiveness acid vapors, tunable optical signals. Upon exposure the fluorescence shifts from initial yellow emission green emission, attributable protonation-induced inhibition excited-state intramolecular proton transfer. Under UV irradiation, undergoes red-shift, resulting transformation an enol configuration ketone configuration. Notably, both processes reversible can be restored under daylight. The integration changes vapors CPL signals, waveguides within single crystal paves way application all-organic chiral functional
