Chemists build a zoo of new polymer building blocks
Over the past 40 years, electroactive polymers have found their way into electronics such as transistors, batteries, light-emitting diodes, and solar cells. Built from conjugated building blocks, these materials exhibit conducting or semiconducting properties, the ability to reversibly change color when oxidized and reduced, and in some cases luminescence that can be toggled on and off. Notable examples include polyacetylene, polyaniline, polythiophene, and poly(p-phenylene vinylene).
Chemists and materials scientists working with these materials have lately . . .
