高效的红-绿-蓝（RGB）三色发光切换在由以下组成的双组分固体膜中得到证实：（2Z，2' Z）-2，2'-1，4-二苯撑（3-（4-丁氧基苯基）丙烯腈）（DBDCS）和（2 Z，2' Z）-3，3'-（2，5-双（6-（9 H-咔唑-9-基）己氧基）-1，4-亚苯基）双（2-（3，5-双（三氟甲基）苯基）丙烯腈）（m-BHCDCS）。通过不同的外部刺激，如热、溶剂蒸汽暴露和机械力，实现了具有高比率颜色对比度（对于红色、绿色和蓝色，λ（em）= 594、527、458 nm）的可逆RGB发光切换。结果表明，福斯特共振能量转移的双组分混合物可以有效地切换和关闭，通过超分子控制。
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.
