Optically active covalent organic frameworks and hyperbranched polymers with chirality induced by circularly polarized light

Axial chirality was induced by circularly polarized light to covalent organic frameworks as well as hyperbranched polymers composed of bezene-1,3,5-triyl core units and oligo(benzene-1,4-diyl) as linker units where variation in induction efficiency was rationally interpreted in terms of internal rotation dynamics studied through CPMAS C-13 NMR experiments including CODEX measurements.

Automated summary

Axial chirality was induced in covalent organic frameworks and hyperbranched polymers using circularly polarized light, composed of benzene-1,3,5-triyl core units and oligo(benzene-1,4-diyl) linker units. The variation in induction efficiency was rationalized through internal rotation dynamics studied via CPMAS C-13 NMR experiments, including CODEX measurements.
