Application

10,12-Pentacosadiynoic acid (PCDA) is an amphiphilic diacetylene that can be used:
  • In combination with a semifluorinated tetracosane ((CF3(CF2)7(CH2)15CH3) to synthesize mixed monolayer by photopolymerization.
  • For the conversion of hydrophobic upconverting nanoparticles (UCNPs) to hydrophilic.
  • To synthesize a polymer by combining with pyridine-2-aldoxime for colorimetric detection of malathion.
  • To synthesize a thermochromic sensor constituting polymer fibres with monomeric unit of two PCDA linked by a p-phenylene group (bis-PCDA-Ph).
  • As an inert coating material upon self-assembly and photopolymerization to modify the surface of Fe3O4 nanoparticles.

As they have been designed to undergo colorimetric changes that are dependent on the polarity of solvents, the majority of conventional solvatochromic molecule based sensor systems inevitably display broad overlaps in their absorption and emission bands. As a result, colorimetric
