“…There has been significant interest in developing soluble metal polychalcogenide species, often stabilized with bulky organic ions such as R 4 N þ and R 4 P þ . [31] Examples include (Ph 4 P) 4 [In 2 (Se 4 ) 4 (Se 5 )], [32] (Et 4 N) 3 [Tl 3 Se 3 (Se 4 ) 3 ], [32] (Et 4 N) 2 [Mo(Se 4 )], [33] [Ph 4 As] 2 [WSe(Se 4 ) 2 ], [33] (Ph 4 P) 4 [Cu 2 (Se 4 ) (Se 5 ) 2 ], [34,35] (Ph 4 P) 2 [M(Se 4 ) 2 ] (M ¼ Zn, Cd), and (Ph 4 P) 2 [Sn(Se 4 ) 3 ]. [36] Similar to the monochalcogenide systems, the extra chalcogens in the polychalcogenide structures aid in breaking up M-X-M linkages and introduce more ionic character in the structure, thereby yielding a more soluble material.…”

The quest to develop thin‐film solution processing approaches that offer low‐cost and preferably low‐temperature deposition, while simultaneously providing quality semiconductor characteristics, has become an important thrust within the materials community. While inorganic compounds offer the potential for outstanding electronic properties relative to organic systems, the very nature of these materials rendering them good electronic materials—namely strong covalent bonding—also leads to poor solubility. This review presents a “dimensional reduction” approach to improving the solubility of metal chalcogenide semiconductors, which generally involves breaking the extended framework up into discrete metal chalcogenide anions separated by small and volatile cationic species. The resulting soluble precursor may be solution‐processed into thin‐film form and thermally decomposed to yield the desired semiconductor. Several applications of this principle to the solution deposition of high‐performance active layers for transistors (channel mobility >10 cm2 V−1 s−1), solar cells (power conversion efficiency of as high as 12%), and fundamental materials study will be presented using hydrazine as the deposition solvent.

“…In the following year, 31 researchers succeeded in isolating salts, which contain [Cu 3 (S 4 ) 3 ] 37 ions and are structurally similar to [Cu 3 (S 6 ) 3 ] 37 . In this study, the (Ph 4 P) 4 [Cu 2 S 20 ] salt containing the [S 6 CuS 8 CuS 6 ] 47 ions in which two CuS 6 rings are bound to each other through the bridging S 2À 8 anion was also described. Analogous silver salts containing the [Ag 2 S 20 ] 47 ions were also obtained.…”

Keywords: Copper / Sulfur / Selenium / Tellurium / ClustersThe investigation of coinage metal molecular clusters bridged by chalcogen atoms represents an area of ever increasing activity in recent chemical and material science research. This is largely due to the relatively high ionic and even higher electric conductivity of binary coinage metal chalcogenides, which leads to properties intermediate between those of semiconducting and metallic phases. In addition, the size-dependency of the chemical, physical, and structural properties of substances on going from small molecules to bulk materials is of general interest. Approaches towards the synthesis and investigation of such clusters have included the study of colloidal nanoparticles with a narrow size distribution, as well as the formation and isolation of [a] ϩ49 (0)7247/82-6368 Andreas Eichhöfer (left) was born in Hünfeld, Germany, in 1964. He received his diploma in 1991, and subsequently graduated in 1993 in the group of Prof. D. Fenske at the university of Karlsruhe with a doctoral degree on metal-phosphorous cluster complexes. He then moved to the group of Prof. G. Fritz at the same institute to work on carbosilanes as precursor compounds for the fabrication of SiC fibers. After that he returned to his previous group and became a research scientist at the Institute of Nanotechnology at the Forschungszentrum Karlsruhe in 1999, where he is currently investigating the syntheses and properties of semiconductor cluster compounds. Stefanie Dehnen (center) was born in Gelnhausen, Germany, in 1969. She obtained her diploma from the University of Karlsruhe in 1993 and her doctoral degree in 1996 under the supervision of Prof. D. Fenske on experimental and theoretical investigations of copper sulfide and copper selenide clusters. After a postdoctoral stay with Prof. R. Ahlrichs (1997) she returned to the inorganic chemistry department at the University of Karlsruhe where she is presently preparing her Habilitation. In 1997, she was awarded a Feodor-Lynen-Stipendium of the Alexander-von-Humboldt-Stiftung, and in 1998, she received a Margarete-von-Wrangell-Habilitations-Stipendium of the state of Baden-Württemberg. Her current research interests comprise the synthesis, structural elucidation and chemical reactivity of binary or ternary polyanions of main group elements.
