Chiral two-dimensional conjugated metal-organic frameworks with high spin polarization.

ABSTRACT: Two-dimensional conjugated metal-organic frameworks have garnered significant research interest as emerging candidates for organic 2D crystal materials. In classical 2D crystals, chirality can give rise to unique physical phenomena; however, the precise implantation of chirality into 2D c-MOFs has yet to be demonstrated. Here, we demonstrate an example of chiral 2D c-MOFs obtained through the side chain-induced chirality amplification strategy to achieve tunable chiral expression, enabling notable chirality amplification. Chiral substitutions induce distortions in the 2,3,7,8,12,13-hexaiminotriindole conjugated ligand along distinct orientations, effectively transferring their chirality to the conjugated backbone. The resulting frameworks exhibit tunable chirality through steric control, w
