- 論文の詳細を見る
Rotational barriers in 9-[2-(substituted methyl)-1-naphthyl]fluorenes are found not significantly affected by the substituent on the methyl group, ΔG<SUP>\neweq</SUP>'s being <I>ca.</I> 29 kcal/mol at 373 K. Populations of <I>sp</I>- and <I>ap</I>-rotamers at equilibriums show that the <I>sp</I> form is favored to some extent and the results are attributed to entropy factor. OH···π interaction is detected in the <I>ap</I> form of 9-(2-hydroxymethyl-1-naphthyl)fluorene.
