Millimeter thick bulk materials are needed to facilitate the design of thermoelectric devices. While submicrometer-thin films of organic semiconductors are needed for fundamental spectroscopic studies, they are not ideal for the construction of devices, unless folded or wrinkled. In my talk, I will discuss our recent work on the preparation of conducting bulk materials, from foams to fibers, and explore the interplay of electrical and mechanical properties. Further, I will discuss some of the challenges related to doping of bulk materials, as well as the (in)stability of the doped state. Finally, I will present prototype textile and 3D-printed devices that can be manufactured with bulk materials.
