Chiral two-dimensional metal–organic frameworks based on Zn(salen) ligands: subcomponent self-assembly and circularly polarised luminescence

Solvothermal subcomponent self-assembly of 2-hydroxy-3-(pyridin-4-yl)benzaldehyde, chiral diaminocyclohexane, and Zn( ii ) ions offered a pair of two-dimensional chiral metal–organic frameworks, which display circularly polarised luminescence.
