Product Introduction
4,4′-Stilbenedicarboxylic acid (SDA) is a luminescent ligand that is useful as an organic linker due to the presence of two carboxylic groups, which form bridges between metallic centers. It has conjugated aromatic rings that facilitate the formation of a rigid linker.
Application
SDA can be used in the hydrothermal synthesis of three-dimensional (3D) metal-organic frameworks, which have potential usage in sensing, drug delivery, luminescence, and gas adsorption. It may also be used in energy storage applications such as supercapacitors and batteries.

| Description | This compound belongs to the class of organic compounds known as stilbenes. These are organic compounds containing a 1,2-diphenylethylene moiety. Stilbenes (C6-C2-C6 ) are derived from the common phenylpropene (C6-C3) skeleton building block. The introduction of one or more hydroxyl groups to a phenyl ring lead to stilbenoids. |
