the self-assembly process. The elongated tris-bipyridine ligand BII with oxypropylene bridges forms a tetranuclear circularhelicate [4]cH, whose structure has been confirmed by crystal structure determination. The possible oligomeric combinations of tris-bipy ligands and iron(II) ions may be considered to constitute the potential members of a virtual combinatorial library, generated via dynamic combinatorial
三联吡啶配体 BI 和 BII 与铁 (II) 盐的自组装产生显示环状双螺旋型结构的多核复合物,称为环状螺旋 [n]cH(n 级)。BI 中配体中的联吡啶单元通过亚乙基桥连接,获得五核或六核结构 [5]cH 和 [6]cH,这取决于自组装过程中存在的阴离子。带有氧化丙烯桥的延长的三联吡啶配体 BII 形成四核环状螺旋 [4]cH,其结构已通过晶体结构测定得到证实。tris-bipy 配体和铁 (II) 离子的可能低聚组合可以被认为构成虚拟组合库的潜在成员,通过动态组合化学生成,
