TCI D3390 4,4''-Diamino-p-terphenyl is a linear aromatic diamine built from three benzene rings connected in a para arrangement, with an amino group at each end of the molecule. The compound belongs to the material building block family and is classified more specifically as a linker for Covalent Organic Frameworks (COFs). Its role in the laboratory is to act as a rigid connecting rod that ties molecular nodes together into an ordered porous network, most commonly through condensation reactions with polyfunctional aldehydes that form the imine bonds serving as the backbone of the resulting crystalline framework.
The main characteristics that make this compound a preferred choice are its rigidity and its molecular length. Three aromatic rings joined in the para position produce an almost perfectly straight geometry, so the distance between framework nodes can be predicted reliably, and the pore size of the resulting framework can be designed to be larger than what is achievable with shorter linkers such as benzidine or phenylenediamine. The extended conjugated system also gives the molecule attractive electronic and optical behaviour, including charge transport capability and light absorption, which is valuable in photocatalytic materials and organic semiconductors. The terminal amino groups remain reactive toward carbonyl partners, making the linker straightforward to incorporate into framework syntheses.
In Indonesian laboratories, this linker is typically used in university and institutional research groups working on porous materials, catalysis, and organic electronics. It is normally purchased in research quantities for solvothermal or condensation syntheses carried out on a small scale, where a rigid diamine of defined length is required to control pore dimensions. Researchers preparing imine-linked frameworks for gas adsorption, separation, or photocatalysis studies generally keep it as a standard building block alongside polyfunctional aldehyde nodes.
- Covalent Organic Framework synthesis: serves as the rigid ditopic linker that condenses with polyfunctional aldehydes to build ordered, crystalline imine-linked porous networks with predictable node-to-node spacing.
- Pore size engineering: its three para-linked rings give a longer straight span than benzidine or phenylenediamine, allowing researchers to design frameworks with deliberately larger pore openings.
- Photocatalytic material development: the extended conjugation across the terphenyl core supports light absorption, making the resulting frameworks suitable candidates for light-driven catalytic investigations.
- Organic semiconductor research: the long conjugated system contributes charge transport capability, so frameworks and polymers built from this diamine are studied for electronic and optoelectronic behaviour.
- Imine and Schiff base chemistry: the two reactive terminal amino groups condense readily with aldehyde partners, providing a dependable route into extended imine-based polymers and model compounds.

Store the container tightly closed in a cool, dry, and well-ventilated area, protected from direct sunlight and away from oxidising agents and acids. Aromatic amines are best kept in their original amber or opaque containers, or in tightly sealed glass vessels, to limit exposure to air, moisture, and light. Handle the solid inside a fume hood and avoid generating dust; wear nitrile gloves, safety goggles, and a laboratory coat, and avoid all skin contact and inhalation. Weigh out only the amount required and reseal the container promptly afterwards. Wash hands thoroughly after handling, keep the material clearly labelled, and dispose of residues and contaminated consumables as chemical waste according to institutional procedures. Always consult the manufacturer's Safety Data Sheet before first use.
