A novel π-chromophoric 1,4-bis(anthracenylethynyl)benzene (BAB)-based highly emissive J-aggregated organogel has been synthesized and characterized. Single-crystal structure determination of asymmetric π-chromophoric bola-amphiphilic (dodecyl and triethyleneglycolmonomethylether containing side chains of bis(anthracenylethynyl)benzene) supports J-aggregation. Further, a photochromic acceptor chromophore, 4,4'-(perfluorocyclopent-1-ene-1,2-diyl)bis(5-methylthiophene-2-carbaldehyde), is noncovalently encapsulated in the gel and photoswitching studies have been performed based on photochromic Förster resonance energy transfer. The modulated emission of the processable soft material is further exploited for rewritable display. However, (dodecyl side chain on both sides) does not show gelation property due to its low solubility.
一种基于新型π发色团1,4-双（蒽乙炔基）苯（BAB）的高发射性J-聚集有机凝胶已被合成并表征。不对称π发色团双性两亲物（含有双（蒽乙炔基）苯侧链的十二烷基和三乙二醇单甲醚）的单晶结构测定支持J-聚集。此外，一种光致变色受体发色团，4,4'-（全氟环戊-1-烯-1,2-二基）双（5-甲基噻吩-2-甲醛），被非共价包封在凝胶中，并基于光致变色Förster共振能量转移进行了光开关研究。可加工软材料的调制发射被进一步用于可重写显示。然而，（两侧均为十二烷基侧链）由于其低溶解度而不显示凝胶化性质。
