“…333 The full two shells around one gold atom 55 cluster stabilized with 12 triphenylphosphine and 6 Cl ligands is one of the first examples. 419 It is straightforward that layers of such compounds have also been irradiated with charged particles in order to change the properties. Partially altered material results in nanocomposites with strongly changing electrical properties.…”

Beams of electrons and ions are now fairly routinely focused to dimensions in the nanometer range. Since the beams can be used to locally alter material at the point where they are incident on a surface, they represent direct nanofabrication tools. The authors will focus here on direct fabrication rather than lithography, which is indirect in that it uses the intermediary of resist. In the case of both ions and electrons, material addition or removal can be achieved using precursor gases. In addition ions can also alter material by sputtering ͑milling͒, by damage, or by implantation. Many material removal and deposition processes employing precursor gases have been developed for numerous practical applications, such as mask repair, circuit restructuring and repair, and sample sectioning. The authors will also discuss structures that are made for research purposes or for demonstration of the processing capabilities. In many cases the minimum dimensions at which these processes can be realized are considerably larger than the beam diameters. The atomic level mechanisms responsible for the precursor gas activation have not been studied in detail in many cases. The authors will review the state of the art and level of understanding of direct ion and electron beam fabrication and point out some of the unsolved problems.

“…To this end we recorded the 31 P and 77 Se NMR spectra of Ph 3 P[Se] and dppf[Se] 2 in toluene as the benchmark for this comparison as well, since the underlying phosphanes Ph 3 P and dppf are extremely popular and useful ligands in many synthetic applications. 15,16,[61][62][63][64][65][66][67][68][69][70][71][72][73][74][75][76][77] The 1 J P-Se for compound 5 (723 Hz) is significantly lower than the corresponding values for Ph 3 P[Se] (732 Hz in CDCl 3 ; 78 758 Hz in toluene-d8, see Fig. S61 in ESI file ‡) and dppf[Se] 2 (737 Hz in CDCl 3 ; 59,79 761 Hz in toluene-d8, see Fig.…”

“…Thereafter, major interests in ligand-coordinated gold clusters moved to heterometallic, higher-nuclearity (e.g., Au 39 , Au 55 ), and thiolate-capped families. However, the interests in ultrasmall molecular PGCs have recently revisited [8,[53][54][55] in relation to the advances of structural chemistry of thiolate-capped clusters. Further, the use of state-of-the-art analytical instruments together with the advanced computation technology has opened the door to unusual cluster species.…”

Synthetic techniques, geometrical structures, and electronic absorption spectra of phosphine-coordinated pure-gold molecular clusters (PGCs) accumulated over 40 years are comprehensively collected especially for those with unambiguous X-ray crystal structures available. Inspection of the electronic absorption spectra from geometrical aspects reveals that their optical properties are highly dependent on the cluster geometries rather than the nuclearity. Recent examples of unusual clusters that show unique color / photoluminescence properties and their utilization for stimuli-responsive modules are also presented.
