The fluorinated tolane and bistolane derivatives containing fluorinated aromatic rings and demonstrated their intense photoluminescence (PL) characteristics in crystalline powder states was developed. Mols. showing varied PL behavior with a change in the mol. aggregated structures was focused . We synthesized novel fluorinated tolane dyads consisted fluorinated tolane-based π-conjugated scaffolds and flexible alkylene linkages controlled both the electron-d. distribution and mol. aggregated states. Fluorinated tolane dyads connected with an alkylene linkage showed blue PL in a dilute solution, but the PL efficiency achieved was low. In contrast, the crystalline powder of tolane dyad substrates exhibited dual emission-relatively intense blue to deep blue PL-originating from monomer and aggregate emission. The PL behavior changed significantly with the alkylene linkage and the application of a mech. stimulus to the crystalline powder sample. The fluorinated tolane dyads served as stimulus-responsive photoluminescent materials suitable for optical applications was developed .
