Abstract
We synthesized naphthyl end-capped divinylbenzenes, in which naphthyl replaces phenyl as the substituent at the terminal positions of the oligo-p-phenylenevinylenes, and investigated the performance of organic field-effect transistors (OFETs), air stability and molecular packing in poly- and single-crystalline films. The OFETs exhibited field-effect hole mobility up to 0.21 cm2 Vâ1 sâ1 when the organic semiconductor was evaporated on substrate at 90 °C. Field-effect mobility in air at a controlled temperature of 30 °C and high humidity of 80% was almost constant for a period of up to 220 days, indicating that the material is a very stable organic semiconductor in air.
