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.

Chiral noble metal nanoparticles has recently gained great interest due to their potential applications including ultrasensitive chiral recognition and asymmetric synthesis. We anticipate that they could be utilized to induce asymmetric photo-polymerization reactions with high enantioselectivity and reactivity. Here, we

Noble metal anisotropic nanostructures have achieved a growing interest in both academic and industrial domains mostly because of their shape-dependent plasmonic properties in the near-infrared region. In this paper, gold and gold-silver anisotropic nanostructures were synthesized in very high shape-yields
