Four BINOL-based bis(4-pyridyl) ligands were synthesised in enantiopure and racemic form. These ligands form metallosupramolecular [(dppp)2M2L2] rhombi with cis-protected [(dppp)Pd]2+ and [(dppp)Pt]2+ ions. In principle, racemic ligands can self-assemble into three stereoisomeric rhombi. The degree of self-sorting in the self-assembly process crucially depends on the substitution pattern and the resulting
四种基于 BINOL 的双 (4-吡啶基) 配体以对映体纯和外消旋形式合成。这些配体与顺式保护的 [(dppp)Pd]2+ 和 [(dppp)Pt]2+ 离子形成金属超分子 [(dppp)2M2L2] 菱形。原则上,外消旋配体可以自组装成三个立体异构菱形。自组装过程中的自分类程度主要取决于取代模式和 V 形配体的弯曲角以及使用外消旋配体时组装内的空间拥挤程度。因此,这些过程要么以自恋的自我识别方式导致同手性组装,要么以社会自我歧视的方式导致异手性组装,要么以非选择性方式进行,如核磁共振谱、质谱和单晶 X 射线衍射所证明的.
