Abstract
Porous Metal–Organic Frameworks (MOFs) engineered
with light-sensitive organic linkers provide adaptable architectures for modern
gas sequestration and environmental remediation schemes. In this investigation,
a 3D zinc (II) coordination network, [Zn (ABDC)(DMF)] n (Zn-ABDC), was
successfully fabricated under solvothermal conditions using 4,4'-(diazenediyl)
dibenzoic acid (H2ABDC). Systematic structural profiling by PXRD, FTIR, TGA,
electron microscopy, and physisorption methods established the formation of a
phase-pure framework possessing permanent microporosity (SBET=780 m2/g) along
with thermal resistance up to 380 °C. At 273 K and 1 bar, Zn-ABDC exhibits a
high CO2 binding capacity (3.8 mmol/g), governed predominantly
by strong electrostatic dipole–quadrupole interactions with the central azo
(−N=N−) active sites. Additionally, the material acts as an effective
visible-light photocatalyst, attaining 94% degradation of Methylene Blue (MB)
dye within 90 min. The architecture also displays potential for
light-stimulated, on-demand gas release and selective luminescent chemical sensing.
