Outline of Final Research Achievements

Control of the electron status of π-conjugated materials to optimize their optoelectrical properties by noncovalent bonding such as hydrogen bonding (H-bonding), protonation and halogen bonding has been intensively investigated because these interactions reversibly vary the dynamic features, morphology, processing characteristics and electrooptical properties of the materials without synthetic modification. We have reported the application of such noncovalent bonding to tune the optical properties of mechanochromic luminescent (MCL) compounds. MCL is isothermal changes in solid-state photolumienscent (PL) color in response to mechanical stimuli. We succeeded in controlling the emergence of MCL behavior by acid. We synthesized novel mechano-inert pyridyne terminated luminophore, which could exhibit MCL behavior by combining acid. The dye switched blue shift and red shift change in PL color upon mechanically grinding by changing acid spices.
