Used as a versatile bridging ligand in coordination chemistry, enabling the formation of metal-organic frameworks and supramolecular architectures. Its ability to coordinate with metal ions through nitrogen atoms at both ends makes it ideal for constructing extended networks with tunable porosity and functionality. Employed in the development of sensors and catalytic systems due to its rigid structure and electron-donating properties. Also finds use in photoresponsive materials, where the azo group allows for reversible trans-cis isomerization upon light exposure, useful in molecular switches and smart materials.
