Highly efficient red-green-blue (RGB) tricolor luminescence switching was demonstrated in a bicomponent solid film consisting of (2Z, 2' Z)-2,2'-(1,4-phenylene)bis(3-(4-butoxyphenyl) acrylonitrile) (DBDCS) and (2Z, 2' Z)-3,3'-(2,5-bis(6-(9H-carbazol-9-yl)hexyloxy)-1,4-phenylene)bis(2-(3,5-bis(trifluoromethyl) phenyl) acrylonitrile) (m-BHCDCS). Reversible RGB luminescence switching with a high ratiometric color contrast (lambda(em)= 594, 527, 458 nm for red, green, and blue, respectively) was realized by different external stimuli such as heat, solvent vapor exposure, and mechanical force. It was shown that Forster resonance energy transfer in the bicomponent mixture could be efficiently switched on and off through supramolecular control.
