self-assembly mechanism. Molecular stellation of the trimeric hexagon [Cd6L23] gave rise to the exclusive self-assembly of star hexagon [Cd18L16L33] through complementary ligand pairing between the ditopic and octatopic tectons. To understand how the intermolecular heteroleptic complexation influenced the self-assembly pathway, the star hexagon was truncated into two triangular fragments, [Cd12L13L43]

配体配对产生了星形六边形 [Cd18L16L33] 的独家自组装。为了了解分子间杂配复合如何影响自组装途径,星形六边形被截断为两个三角形片段,[Cd12L13L43] 和 [Cd12L13L53]。在[Cd12L13L43]的自组装过程中,L1可以调控六位
配体L4的构象运动以促进随后的配位事件,这是多组分自组装成功的关键步骤。相比之下,
