General description

5-Cyano-1,3-benzenedicarboxylic acid (CYDC) is an organic linker that can be used as a ligand in the formation of metal-organic frameworks (MOFs). It is reported to show luminescence in the solid-state at λem= 360 and 372 nm and a small band at 481 nm upon excitation at λexc= 320 nm.
We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Greener Chemistry. This product has been enhanced for energy efficiency. Find details here.

Application

CYDC is a carboxylate ligand that can be used in the development of new materials for applications in light-emitting diodes (LEDs) and chemical sensors. It can also be used in the formation of multivariate MOFs for potential usage in gas storage, catalysis, and biomedicine.
Metal organic frameworks (MOFs) may be formed by the hydrothermal reaction of 5-Cyano-1,3-benzenedicarboxylic acid ligand with metallic salts of cadmium, zinc and cobalt in the presence of sodium azide.
