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.
