Researchers Make a Major Step Forward in Organic Electronics

It has been difficult to find a sufficiently stable polymer material, one that can operate in water media and in which the long polymer chains can sustain high current when the material is doped.
N-type materialIn an article in the prestigious scientific journal Advanced Materials, Simone Fabiano, head of research in the Organic Nanoelectronics group at the Laboratory of Organic Electronics, presents, together with his colleagues, results from an n-type conducting material in which the ladder-type structure of the polymer backbone favours ambient stability and high current when doped. One example is BBL, poly(benzimidazobenzophenanthroline), a material often used in solar cell research.

“We have used spray-coating to produce films up to 200 nm thick. These can reach extremely high conductivities,” says Simone Fabiano.
The method can also be successfully used together with printed electronics across large surfaces.
Hengda Sun has also shown that the circuits function for long periods, both in the presence of oxygen and water.
“Resistors are needed in logical circuits that are based solely on p-type electrochemical transistors. These are rather bulky, and this limits the applications that can be achieved. With an n-type material in our toolbox, we can produce complementary circuits that occupy the available space much more efficiently, since resistors are no longer required in the logical circuits,” says Magnus Berggren, professor of organic electronics and head of the Laboratory for Organic Electronics.
