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] CCH–) interfacial linkages rather than Pt–acetylide (Pt–C [triple bond, length as m-dash] C–) and platinum–hydride (Pt–H) bonds.
