Chiral induction in boron imidazolate frameworks: the construction of cage-based absolute helices

Two cage-based boron imidazolate helices were prepared in achiral reaction systems by mixing a C-3 symmetric rigid ligand, KBH(bim)(3), and a long flexible dicarboxylic acid ligand. The presence of an appropriate chiral inducer can control the helical orientation of bulk samples, which further acts on the enantioselective separation of racemic 1-phenylethanol.

Automated summary

By mixing different ligands in achiral reaction systems, cage-based boron imidazolate helices were prepared, with the presence of an appropriate chiral inducer controlling the helical orientation and influencing the enantioselective separation of racemic 1-phenylethanol.
