Optical Absorption Spectra of Nanocrystal Gold Molecules
Marcos M. Alvarez,Joseph T. Khoury,T. Gregory Schaaff,Marat N. Shafigullin,Igor Vezmar,Robert L. Whetten +5 more
TL;DR: The optical absorption spectra of a series of nanocrystal gold molecules, passivated by a compact monolayer of n-alkylthiol(ate)shave have been measured across the electronic range (1.1−4.0 eV) in dilute solution at ordinary temperature as mentioned in this paper.
Journal ArticleDOI
Photophysical properties of C60
James W. Arbogast,Aleksander P. Darmanyan,Christopher S. Foote,Yves Rubin,François Diederich,Marcos M. Alvarez,Samir J. Anz,Robert L. Whetten +7 more
TL;DR: A number of important photophysical properties of C{sub 60} have been determined, including its lowest triplet state energy (near 33 kcal/mol), lifetime, and triplet-triplet absorption spectrum as mentioned in this paper.

Nanocrystal gold molecules
Robert L. Whetten,Joseph T. Khoury,Marcos M. Alvarez,Srihari Murthy,Igor Vezmar,Zhong Lin Wang,Peter W. Stephens,Charles L. Cleveland,W. D. Luedtke,Uzi Landman +9 more
TL;DR: In this article, a series of gold nanocrystals, passivated by self-assembled monolayers (SAMs) of straight-chain alkylthiolate molecules (RS, R) are described.

Gold nanoelectrodes of varied size: Transition to molecule-like charging
Shaowei Chen,Roychelle S. Ingram,Michael J. Hostetler,Jeremy J. Pietron,Royce W. Murray,Royce W. Murray,T. Gregory Schaaff,Joseph T. Khoury,Marcos M. Alvarez,Robert L. Whetten +9 more
TL;DR: A transition from metal-like double-layer capacitive charging to redox-like charging was observed in electrochemical ensemble Coulomb staircase experiments on solutions of gold nanoparticles of varied core size, consistent with new near-infrared spectroscopic data showing an emerging gap between the highest occupied and lowest unoccupied orbitals.
Journal ArticleDOI
Characterization of the soluble all-carbon molecules C60 and C70
Henry O. Ajie,Marcos M. Alvarez,Samir J. Anz,Rainer D. Beck,François Diederich,K. Fostiropoulos,Donald R. Huffman,Wolfgang Kraetschmer,Yves Rubin +8 more
TL;DR: In this paper, the physical and chemical characterization of two new molecular forms of carbon, C{sub 60} and C {sub 70} were reported. But the results demonstrate a high yield of production (14%) under optimized conditions and reveal only C{ sub 60 and Csub 70 in measurable quantity, in an 85:15 ratio.
