From pixels to pores: 3D-(im)printed hierarchically porous polymer monoliths.

ABSTRACT: Bridging molecular recognition with scalable materials is a central challenge in polymer science. Here, we present the first comprehensive characterization of LCD-based 3D-printed molecularly imprinted polymers (3DMIPs) with digitally programmable macrogeometries and tunable hierarchical porosity, revealing their optimization potential. As a case study, 3DMIPs targeting the specific enrichment of cannabidiol (CBD) are demonstrated. A highly porous lattice yields a 10.3-fold CBD enrichment, an imprinting factor of 3.7, and a CBD uptake of 1.65 mg/g, outperforming a coarser analog. Imaging and porosimetry reveal the pore architecture, pore interconnectivity, and pore size distribution, which, together with the macrogeometry, critically influence mass transfer and binding efficiency in these
