[structure: see text] The conformational properties of intramolecularly hydrogen-bonded dendrimers constructed from (S)-1,1'-bi-2-naphthol as a chiral central core are described. Circular dichroism studies revealed that chirality transfer to the periphery occurs only when sterically demanding terminal esters are employed and when packing interactions are present.

2-萘酚作为手性中心核构成的分子内氢键结合的树枝状聚合物的构象性质。圆二色性研究表明,仅当使用空间要求的末端酯并且存在堆积相互作用时,手性才发生向外围的转移。
