Examples
-
The soliton in polyacetylene was born with the observation of an electron spin resonance (esr) signal in the pure material where there should not have been one.
-
These two properties are essential for the formation of any film, and they were inherent in polyacetylene.
-
Since we had found previously that by adding bromine to the golden (SN) x material, we could increase its conductivity tenfold, we thought that perhaps the impurity in the polyacetylene was acting as a dopant and was actually increasing the conductivity of the polyacetylene, rather than decreasing it.
-
In 1977 a paper entitled "Synthesis of electrically conducting organic polymers: Halogen derivates of polyacetylene" was published in the Journal of the American
The Nobel Prize in Chemistry: The Development of Modern Chemistry 2010
-
As a result, we found that the emergence of electrical conductivity on the doped polyacetylene was due to the creation of carbocations or positively charged solitons associated with withdrawing of p electrons from polyacetylene by the dopant when iodine was used as an acceptor dopant.
-
The initial purpose of this study was to determine the polymierization mechanism of polyacetylene using the Ziegler-Natta catalysts.
-
We succeeded in simultaneously polymerizing acetylene and synthesizing uniaxially oriented polyacetylene films by orienting the catalyst solution of liquid crystal solvent under flow condition or magnetic field.
-
I could say that nature had prepared us for the way to make polyacetylene film.
-
Later, through the measurements of various absorption spectra of this thin film, we determined the molecular structure of polyacetylene, and thus, we fulfilled the initial purpose of our work.
-
Initially I was reluctant to work in this field, but actually, I realize that my experiences in this laboratory were of great importance to me when I worked with polyacetylene later on.
