摘要:
Photoconductive organic polymers useful in the preparation of photodetectors and photoconductive devices comprise a transrich polyphenylacetylene. The photoconductive properties may be further enhanced by the addition of an electron-acceptor dopant, and sensitized to selected spectral regions by the addition of a selected dye.
摘要:
The invention relates to a doped polyacetylene film for forming an organic semiconductor or even a conductor of a metallic type. It serves to make the doping more homogeneous and improves the stability over a period of time. The process consists of using as the dopant a salt of an element such as chrome, nickel, iron, titanium, tungsten, or molybdenum belonging to the transition metals, or a salt of an element such as europium or ytterbium belonging to the lanthanides. Doping takes place by immersing the film in a solution having a low dopant concentration, e.g. in toluene, and maintaining the system at low pressure and ordinary temperature for a period of a few days, as a function of the desired doping level and conductivity.

摘要:
This invention relates to poly(arylacetylene) thermosetting compositions and thermoset resins prepared therefrom. The thermosetting compositions comprise a poly(phenylene oxide) and a polyacetylenically unsaturated prepolymer of a polyacetylenically substituted aromatic compound such as diethynylbenzene. The prepolymer has a number average molecular weight of about 900 to about 12,000 and contains from about 5 to about 20% by weight of terminal acetylenic groups. A representative poly(phenylene oxide) is poly(2,6-dimethyl-1,4-phenylene oxide).
