The challenge of quantitatively forming self-assembled heterodimers without other equilibrium by-products is overcome through self-sorting favored by the introduction of designed shape-complementary moieties. Such a supramolecular strategy based on cucurbit[8]uril-directed dimerization is further applied to generate hetero-chromophore dimers quantitatively, leading to efficient energy transfer (>85 %) upon photoexcitation.
通过引入设计的形状互补部分来促进自分类，克服了在没有其他平衡副产物的情况下定量形成自组装杂二聚体的挑战。这种基于葫芦[8]脲导向二聚化的超分子策略进一步用于定量生成杂生色体二聚体，在光激发时导致有效的能量转移（>85%）。
