V-shaped chiral hosts based on π-extended hematoxylin

Chem Commun (Camb). 2023 Sep 14;59(74):11145-11148. doi: 10.1039/d3cc03631f.

Abstract

Hematoxylin has a V-shaped chiral geometry, but its potential in chiroptical self-assembled materials is underdeveloped. Herein, three novel V-shaped chiral hematoxylin derivatives were synthesized, and they showed extended skeletons as well as photophysical and chiroptical behaviors. Moreover, their host-guest interactions with C60 were investigated. Our findings could aid in the design and synthesis of novel chiral host molecules from natural products.
