Abstract
Eighteen polyacene polymers were synthesized, and their resistivities were found to be of the order of 104–105 ohm‐cm. The resistivity of these polymer semiconductors was found to be sensitive to changes in the conditions of synthesis, changes in the structure of the polymers, and variations of pressure and temperature during experimentation. The forbidden energy gap for these polymers was about 0.5 e.v. Although the formalism of the simple intrinsic semiconductor band model was not strictly applicable to the data on these polymers, such a treatment was found instructive.
