Abstract
Stable platinum nanoparticles were prepared by the self-assembly of 1-dodecyne and dodec-1-deuteroyne onto bare platinum colloid surfaces. The nanoparticles exhibited consistent core size and optical properties. FTIR and NMR measurements confirmed the formation of Pt-vinylidene (Pt[double bond, length as m-dash]C[double bond, length as m-dash]CH-) interfacial linkages rather than Pt-acetylide (Pt-C[triple bond, length as m-dash]C-) and platinum-hydride (Pt-H) bonds.
摘要
通过将1-十二炔和1-氘代十二炔自组装到裸露的铂胶体表面制备了稳定的铂纳米颗粒。这些纳米颗粒表现出一致的核心尺寸和光学性质。傅里叶变换红外光谱（FTIR）和核磁共振（NMR）测量证实形成了亚乙烯基铂（Pt=C=CH-）界面键，而非乙炔基铂（Pt-C≡C-）和氢化铂（Pt-H）键。
