ZIF-90 (Zn(ICA)2, where ICA = imidazolate-2-carboxaldehyde) is a sodalite-topology zeolitic imidazolate framework constructed from tetrahedrally coordinated Zn^{2+} nodes connected by 2-formylimidazolate linkers. It is isostructural with ZIF-8, but the replacement of the non-polar 2-methyl group (-CH3) with an electron-rich, polar aldehyde group (-CHO) provides both higher polarity for gas separation and a reactive platform for post-synthetic covalent modification.

The key structural and functional features of theZIF-90 are: (1) Sodalite (SOD) Pore Architecture: Central Pore Cavity: ~ 11.2 Å spherical cage. Pore Aperture: 6-membered ring windows with a nominal crystallographic aperture of ~ 3.5 Å (effective dynamic aperture ~ 3.5–3.8 Å. (2) Polar Aldehyde (-CHO) Pore Environment: The protruding carbonyl oxygens (C=O) project directly into the apertures and cages, providing strong local dipole fields that enhance electrostatic interactions with polar/quadrupolar gas molecules (such as CO2 and SO2). (3) Chemical & Thermal Stability: Thermally stable up to ~ 300–350°C in air/inert atmospheres. Resists boiling water, alcohols, and neutral-to-alkaline aqueous solutions, though like most ZIFs, it is sensitive to acidic environments (pH < 4–5).
