    摘要： Polysilanes, inks containing the same, and methods for their preparation are disclosed. The polysilane generally has the formula H-[(AHR)n(c-AmHpm-2)q]—H, where each instance of A is independently Si or Ge; R is H, -AaHa+1Ra, halogen, aryl or substituted aryl; (n+a)≧10 if q=0, q≧3 if n=0, and (n+q)≧6 if both n and q≠0; p is 1 or 2; and m is from 3 to 12. In one aspect, the method generally includes the steps of combining a silane compound of the formula AHaR14-a, the formula AkHgR1′h and/or the formula c-AmHpmR1rm with a catalyst of the formula R4xR5yMXz (or an immobilized derivative thereof) to form a poly(aryl)silane; then washing the poly(aryl)silane with an aqueous washing composition and contacting the poly(aryl)silane with an adsorbent to remove the metal M. In another aspect, the method includes the steps of halogenating a polyarylsilane to form a halopolysilane; and reducing the halopolysilane with a metal hydride to form the polysilane. The synthesis of semiconductor inks via dehydrocoupling of silanes and/or germanes allows for tuning of the ink properties (e.g., viscosity, boiling point, and surface tension) and for deposition of silicon films or islands by spincoating, inkjetting, dropcasting, etc., with or without the use of UV irradiation.

    摘要： Compositions, inks and methods for forming a patterned silicon-containing film and patterned structures including such a film. The composition generally includes (a) passivated semiconductor nanoparticles and (b) first and second cyclic Group IVA compounds in which the cyclic species predominantly contains Si and/or Ge atoms. The ink generally includes the composition and a solvent in which the composition is soluble. The method generally includes the steps of (1) printing the composition or ink on a substrate to form a pattern, and (2) curing the patterned composition or ink. In an alternative embodiment, the method includes the steps of (i) curing either a semiconductor nanoparticle composition or at least one cyclic Group IVA compound to form a thin film, (ii) coating the thin film with the other, and (iii) curing the coated thin film to form a semiconducting thin film. The semiconducting thin film includes a sintered mixture of semiconductor nanoparticles in hydrogenated, at least partially amorphous silicon and/or germanium. The thin film exhibits improved conductivity, density, adhesion and/or carrier mobility relative to an otherwise identical structure made by an identical process, but without either the semiconductor nanoparticles or the hydrogenated Group IVA element polymer. The present invention advantageously provides semiconducting thin film structures having qualities suitable for use in electronics applications, such as display devices or RF ID tags, while enabling high-throughput printing processes that form such thin films in seconds or minutes, rather than hours or days as with conventional photolithographic processes.

    摘要： A method of making hydrogenated Group IVA compounds having reduced metal-based impurities, compositions and inks including such Group IVA compounds, and methods for forming a semiconductor thin film. Thin semiconducting films prepared according to the present invention generally exhibit improved conductivity, film morphology and/or carrier mobility relative to an otherwise identical structure made by an identical process, but without the washing step. In addition, the properties of the present thin film are generally more predictable than those of films produced from similarly prepared (cyclo)silanes that have not been washed according to the present invention. The present invention advantageously provides semiconducting thin film structures having qualities suitable for use in electronics applications, such as display devices or RF ID tags, while enabling high-throughput manufacturing processes that form such thin films in seconds or minutes, rather than hours or days as with conventional photolithographic processes.
