Significant advances have been made in the preparation and application of luminescent hydrogen-bonded organic frameworks (HOFs) recent years. These materials exhibit unique structural flexibility accommodating guest molecules, rendering them promising candidates for dynamic applications. Herein, a 2D HOF material is presented, constructed by binary assembly 5,5'-bis(azanediyl)oxalyl diisophthalic acid tetra(pyrid-4-ylphenyl)ethylene to achieve circularly polarized luminescence (CPL) with aid chiral guests. Efficient chirality transfer CPLs are realized incorporating carvone molecules into 1D channels HOFs through hydrogen bonding. As result interlayer contraction upon desorption, these display emission colors varying from cyan yellow. The method bonding-enhanced host-guest combination desorption-triggered provides simple chiroptical properties porous materials.
