2',5'-Bis(hexyloxy)-[1,1':4',1''-terphenyl]-4,4''-dicarbaldehyde

This dialdehyde with hexyloxy chains is a white to off-white crystalline powder with a literature melting point of 174-178°C and a predicted boiling point of 603.5°C.The predicted density is 1.066 g/cm³.Storage under nitrogen at 2-8°C is recommended.Its solubility profile is similar to its decyloxy analog:low water solubility but good solubility in common polar organic solvents.The two formyl groups are sensitive to oxidation and strong nucleophiles.

4-[4-(4-Formylphenyl)-2,5-dihexoxyphenyl]benzaldehyde is a symmetrical,π-extended dialdehyde monomer with intermediate-length hexyloxy solubilizing groups.Compared to the decyloxy analog,the shorter C6 chains offer a balance between adequate solubility and reduced steric bulk,which can influence the packing and porosity of resulting polymeric or macrocyclic structures.Its design is optimal for creating solution-processable,conjugated porous materials where control over the alkoxy chain length is critical for tuning material properties.

1.Pharmaceutical Synthesis
Can be utilized to construct shape-persistent organic cages via[4+4]or other cyclization reactions.These cages can act as molecular containers for drug molecules,potentially improving solubility,stability,or enabling targeted delivery.The aldehydes provide handles for post-assembly functionalization.

2.Agrochemical R&D
Similar to its analog,it is investigated for creating polymer-based controlled-release systems.The slightly shorter chains may alter the degradation rate and release profile of the encapsulating matrix,allowing fine-tuning for specific agricultural applications.

3.Functional Material Synthesis
An ideal building block for linear conjugated polymers via the Heck reaction or Knoevenagel condensation(using the aldehydes).Polymers derived from this monomer,due to its planar,biphenyl-dialdehyde core and alkoxy side chains,are promising for organic photovoltaics(OPVs)as electron-accepting materials or as components in perovskite solar cell hole-transport layers.

4.Organic Synthesis Building Block
Used in the synthesis of discotic liquid crystals.The central core can promoteπ-πstacking,while the hexyloxy chains provide fluidity.Such materials can self-assemble into columnar phases with potential applications in organic semiconductors and photoconductive devices.
