Poly(3-hexylthiophene) monolayer nanowhiskers

We report poly(3-hexylthiophene) (P3HT) nanowhiskers of monolayer thickness which self- assemble in a dilute solution. These nanowhiskers are tens of micrometers in length, similar to 30 nm in width, but only 1.6 nm in thickness, corresponding to the height of P3HT in the side-chain direction. The field-effect mobility of these nanowhiskers reached 1.3 x 10(-2) cm(2) V-1 s(-1).
