Timeline

Hideki Shirakawa (白川 英樹) is a Japanese chemist, engineer, and Professor Emeritus at the University of Tsukuba and Zhejiang University.

He is best known for his discovery of conductive polymers.

1961

Shirakawa graduated from Tokyo Institute of Technology (Tokyo Tech) with a bachelor's degree in chemical engineering in 1961, and his doctorate in 1966.

Afterward, he obtained the post of assistant in Chemical Resources Laboratory at Tokyo Tech.

While employed as an assistant at Tokyo Institute of Technology (Tokyo Tech) in Japan, Shirakawa developed polyacetylene, which has a metallic appearance.

1975

This result interested Alan MacDiarmid when MacDiarmid visited Tokyo Tech in 1975.

1976

In 1976, he was invited to work in the laboratory of Alan MacDiarmid as a post-doctoral fellow at the University of Pennsylvania.

The two developed the electrical conductivity of polyacetylene along with American physicist Alan Heeger.

1977

In 1977 they discovered that doping with iodine vapor could enhance the conductivity of polyacetylene.

1979

In 1979, Shirakawa became an assistant professor in the University of Tsukuba; three years later, he advanced to a full professor.

1991

In 1991 he was appointed as Tsukuba's Chief of Science and Engineering Department of Graduate School (until March, 1993), and as Tsukuba's Chief of Category #3 group (until March, 1997).

Shirakawa's research on conductive polymers can be broken down into four main categories: polyacetylene thin film synthesis, the causation of metallic conductivity due to chemical doping, the creation of conjugated (double or triple bonds in a molecule which are separated by a single bond) liquid crystalline polymers, and acetylene polymerization development that used liquid crystals as solvents.

-The general definition of electrical anisotropy describes the variation of an electrical property depending on the lateral or vertical direction (x,y,z) in which a current flows.

2000

He was co-recipient of the 2000 Nobel Prize in Chemistry jointly with Alan MacDiarmid and Alan Heeger.

Hideki Shirakawa was born in Tokyo, Japan, the second son of a military doctor.

He had one elder and one younger brother and sister.

Olympic marathoner champion Naoko Takahashi is his second cousin-niece.

He lived in Manchukuo and Taiwan during childhood.

Around third grade, he moved to Takayama, Gifu, which is the hometown of his mother.

The three scientists were awarded the Nobel Prize in Chemistry in 2000 in recognition of the discovery.

With regard to the mechanism of electric conduction, it is strongly believed that nonlinear excitations in the form of solitons play a role.

Shirakawa was awarded the 2000 Nobel Prize in Chemistry together with UPenn's physics professor Alan J. Heeger and chemistry professor Alan G. MacDiarmid, "for the discovery and development of conductive polymers".

He also became the first Japanese Nobel laureate who did not graduate from one of the National Seven Universities and the second Japanese chemistry Nobel laureate.

Over the years, Shirakawa has expressed that he does not want the Nobel Prizes to receive too much special treatment from mass media (especially the Japanese media).

He hopes that many vital areas in fields outside the Nobel Prize categories will also become more widely known.

One of his relatives, Hitomi Yoshizawa, is a member of the singing group Morning Musume Morning Girls.

He is also related to Naoko Takahashi, the women's marathon gold medalist of the 2000 Summer Olympics.

2013

On 6 December 2013, the House of Councillors (Japan) approved the bill of the State Secrecy Law.

Shirakawa and physics Nobel laureate Toshihide Maskawa issued a statement saying that the law:

"threatens the pacifist principles and fundamental human rights established by the constitution and should be rejected immediately...(omitted)...Even in difficult times, protecting the freedom of the press, of thought and expression and of academic research is indispensable."
