Mechanochromic luminophores exhibiting rich-colour transitions among multiple states have important potential applications, but few such compounds are known. Herein, chiral self-assembly fabrication is proposed as a valid method to realize a new type of metastable state, which may bring enriched PL colours. A novel chiral fluorophore,ACNS, was synthesized and assembled into helices with specific handedness, showing a tricolour photoluminescence (PL) transition among yellow, green and blue under grinding and other stimuli. The crystallineACNSpowder (B-phase) emits bright sky-blue light. Interestingly, the luminophore assembles into helical nanofibres (Y-phase) with specific handedness, which present yellow fluorescence at 539 nm. Moreover, upon grinding, both Y-phase and B-phase powder change into green-emitting powder (G-Phase) with a PL peak at 498 nm. This strategy is conceptually simple and affords a promising approach to the development of mechanochromic luminophores with multicolour fluorescence switching.

Synthesis and thermal properties of twin dimers containing cyanostilbene derivatives as a mesogenic group
Mihara,Ito,Koide
, p. 69 - 85 (2007/10/03)
We synthesized twin dimers (TDs) with different linking groups between a mesogenic group and a flexible spacer, different spacer length, and different terminal alkyl chain length to clarify the effect of these groups on the mesomorphic properties of the T
