[结构：见正文]树枝状大分子是有吸引力的催化支架，因为催化中心可以分离，催化剂可以回收和重复使用。在这里，我们表明，与更灵活的分子相比，构象受限的分子更容易接近树枝状核心。本文报道的结果对利用树枝状大分子作为催化中人工选择性的支架具有一定的指导意义。
[structure: see text] Dendrimers are attractive scaffolds for catalysis, since catalytic sites can be isolated and the catalysts are recoverable and reusable. Herein, we show that conformationally constrained molecules have better access to dendritic cores compared to the more flexible counterparts. The results reported here should have implications in utilizing dendrimers as scaffolds for artificial selectivity in catalysis.
