The ionization potentials of size- and isomer-selected diamondoids (nanodiamond containing one to five crystal cages) have been measured by means of total-ion-yield spectroscopy. We find a monotonic decrease of the ionization potential with increasing diamondoid size. This experimental result is compared to recent theoretical predictions and comparable investigations on related carbon clusters, the fullerenes, which show isomer effects to be stronger than size dependence.

Electronic structure tuning of diamondoids through functionalization.
This work investigates the changes in electronic structures induced by chemical functionalization of the five smallest diamondoids using valence photoelectron spectroscopy and shows that a linear correlation exists between the HOMO-1 ionization potential and the functional group electronegativity.
Dissociative ionisation of adamantane: a combined theoretical and experimental study.
This paper characterises the dissociative ionisation of adamantane (C10H16) utilising imaging Photoelectron Photoion Coincidence (iPEPICO) spectroscopy and Density Functional Theory (DFT) calculations and finds dissociation channels leading to small cationic hydrocarbons, which may be relevant in the interstellar medium.

Many of the promising new biomedical applications of diamond nanoparticles are moderated by charge transfer reactions, occurring between different surface facets and the surrounding molecules and/or
The influence of a single thiol group on the electronic and optical properties of the smallest diamondoid adamantane.
It is found that the optical properties of the diamondoid are strongly affected due to a drastic change in the occupied states and the lowest unoccupied states remain delocalized at the cluster surface leaving theiamondoid's negative electron affinity intact.

Infrared spectrum and structure of the adamantane cation: direct evidence for Jahn-Teller distortion.
The analysis of the IR spectrum provides the first spectroscopic characterization of this fundamental cycloalkane carbocation in the gas phase and direct evidence for the Jahn-Teller distortion in the (2)A(1) ground electronic state.
Negative electron affinity of adamantane on Cu(111)
Photoelectron spectroscopy is used to show that thick adamantane films on Cu(111) have a negative electron affinity and the valence bands are shifted toward the Fermi energy due to charge transfer from Cu 3d bands.

Molecular limits to the quantum confinement model in diamond clusters.
The results contradict the commonly used and very successful quantum confinement model for semiconductors, which predicts increasing band edge blueshifts with decreasing particle size, and indicate that in the ultimate size limit for nanocrystals a more molecular description is necessary.
Isolation and Structure of Higher Diamondoids, Nanometer-Sized Diamond Molecules

Electron emission from diamondoids: a diffusion quantum Monte Carlo study.
The authors' QMC calculations predict a small exciton binding energy and a negative electron affinity for diamondoids up to 1 nm, resulting from the delocalized nature of the lowest unoccupied molecular orbital, which suggests a range of possible applications of diamondoids as low-voltage electron emitters.
