Abstract

A facile spin-coating method in which a small percentage of the solvent additive, 1-chloronaphthalene (CN), is found to increase the drying time during film deposition, is reported. The field-effect mobility of a PDPPDBTE film cast from a chloroform-CN mixed solution is 0.46 cm2 V-1 s -1. The addition of CN to the chloroform solution facilitates the formation of highly crystalline polymer structures.
