Abstract

Charge transport through a semiconducting nanoparticle assembly is demonstrated. The hole mobility of low and high molecular weight and regioreglular poly(3-hexylthiophene) (P3HT) nanoparticles is on the order of 2 × 10(-4) to 5 × 10(-4) cm(2) V(-1) s(-1) , which is comparable to drop-cast thin films of pristine P3HT. Various methods are employed to understand the nature and importance of the nanoparticle packing.

Keywords: charge transport; conjugated polymers; nanoparticles; poly(3-hexylthiophene) (P3HT); self-assembly.
