The introduction of arylethynyl moieties at the pyrrole α- and β-positions of dipyrrolyldiketone BF complexes as anion-responsive π-electronic molecules was investigated. The arylethynyl-substituted derivatives formed a variety of anion complexes with planar [1+1]- and interlocked [2+1]-type structures in solution and in the solid state. The derivatives with long alkyl chains in the introduced arylethynyl groups also formed mesophases in the form of ion pairs of the anion complexes and a counter cation. The geometries of the constituent anion complexes affected the packing modes of the dimension-controlled assemblies.
研究了在二吡咯二酮BF配合物的吡咯α-和β-位引入芳乙炔基部分作为阴离子响应性π电子分子的情况。芳乙炔基取代的衍生物在溶液和固态中形成了具有平面[1+1]型和互锁[2+1]型结构的多种阴离子配合物。在引入的芳乙炔基中带有长烷基链的衍生物也以阴离子配合物与抗衡阳离子的离子对形式形成了中间相。组成阴离子配合物的几何形状影响了尺寸可控组装体的堆积模式。
