High-performance organic circuits is carefully made using two different materials, but researchers have used a new polymer that performs the function of both materials called ambipolar polymer. The new material and its specs are indicated in the journal Advanced Materials.
Electronics need transistors to have alternating regions that conduct negative and positive charges. They need to be aligned in order to make meaningful circuits. The cost advantage and simplicity is degraded when two necessary materials are involved in complex patterning processes. The ideal solution is to have one material that can transport electrons and holes. The new polymer consists of two alternating units, one that conducts electrons and the other conducts holes. This polymer may also work for solar cells.
