| Research Abstract |
Fabrication of nanoparticles (NPs) in a desired form, especially in a highly anisotropic form such as 1D, has receiving significant attention in recent years in relation to advanced devices. Thymine derivative (Thy), which forms dimer reversibly by UV irradiation with different wavelengths of 270 and 220 nm. The gold nanoparticles functionalized by thymine derivatives (Thy-AuNP) were synthesized by ligand exchange reaction of dodecanthiol protected gold nanoparticles (DT-AuNP). Irradiation of UV light (270 nm) to the Thy-AuNP in THF solution resulted in the formation of 1D arrangement comprising photodimerization of Thymine. TEM observation showed the distance between arranged Thy-DT-AuNPs coincides with the size of dimerized Thy derivative (3.6 nm). Thus, Thy ligands were introduced to opposite positions of Au NPs, as anticipated for Au NPs of 2.6 nm size. When UV with 220 nm was irradiated to THF solution containing arranged Thy-DT-AuNPsThy, 1D ordering disappeared.
