An Iowa State chemist is researching organic polymers that mimic the properties of traditional inorganic semiconductors potentially making 'plastics electronics' applicable in applications like organic solar cells, light-emitting diodes, and thin-film transistors.
Malika Jeffries-EL, an Iowa State assistant professor of chemistry, is working with a variety of benzobisazoles, molecules that are well suited for electrical applications because of their conductivity, or ability to efficiently transport electrons. In addition, the benzobisazoles are stable at high temperatures and can absorb photons.
In the abstract of a presentation Jeffries-EL will present on May 20 at the University of Cincinnati, the professor notes that as a class of materials, polybenzobisazoles "possess many exceptional electronic, optical, and thermal properties and thus are ideally suited for diverse organic semiconducting applications, yet these materials have found limited utility due their lack of solubility in organic solvents."...
