Description
TCI D2115 4,4'-Dicarboxydiphenyl Ether is an aromatic dicarboxylic acid built from two benzene rings joined by an ether bridge, with a carboxyl group at the para position of each ring. The compound is classified as a raw material for Metal Organic Frameworks (MOFs), a family of porous materials formed by connecting metal ions with organic linkers. In laboratory work, this compound serves as the linker or bridging ligand that determines the geometry, pore size, and framework stability of the porous material a researcher intends to synthesise.
The property that makes it a frequent choice lies in its two widely separated, opposed carboxyl groups, combined with an ether bridge that introduces a small degree of angular flexibility between the two aromatic rings. Carboxyl groups are strong coordination sites toward a wide range of metal ions, so the resulting framework tends to be robust, while the not-quite-linear angle of the ether bridge opens the possibility of framework topologies different from those obtained with fully rigid aromatic linkers. This combination of coordination strength and limited flexibility is what makes diphenyl ether type linkers attractive to researchers.
In Indonesian laboratories, materials of this kind are typically used in university and institutional research groups working on porous materials, where the linker is combined with a metal salt under solvothermal conditions and the resulting framework is then characterised. Because the compound functions as a structural building block rather than a routine reagent, it is generally purchased in research-scale quantities and handled as part of a defined synthesis plan rather than as a general-purpose stock chemical.
Laboratory Applications
- Metal Organic Framework synthesis — the two para-oriented carboxyl groups coordinate strongly to metal ions, allowing the linker to define pore dimensions and framework connectivity during assembly.
- Framework topology studies — the ether bridge gives an angular, partially flexible geometry that lets researchers access network topologies unavailable to fully rigid aromatic dicarboxylic linkers.
- Coordination polymer preparation — as a ditopic bridging ligand, it links metal centres into extended one, two, or three dimensional coordination networks for structural investigation.
- Porous materials research — because the linker length and geometry govern pore size, it is used when a specific pore environment is targeted for adsorption or separation studies.
- Organic-inorganic hybrid materials development — it provides the organic component that bonds to inorganic metal nodes, forming hybrid materials whose properties depend on the linker chosen.

Handling and Storage
Store the container tightly closed in a cool, dry, well-ventilated area, away from moisture, direct sunlight, and incompatible materials, and keep it in the original manufacturer packaging or an equivalent chemically resistant, clearly labelled container. Because the material is a fine organic solid, weigh and transfer it in a fume hood or well-ventilated workspace to limit dust generation, and use a spatula rather than pouring where possible. Wear a laboratory coat, safety glasses, and suitable gloves during handling, avoid contact with skin and eyes, and wash hands after use. Follow the manufacturer safety data sheet for detailed guidance, and dispose of residues and contaminated materials through the laboratory chemical waste stream.
