Abstract

A new p-type conjugated copolymer, poly(9,10-diethynylanthracene-alt-9,9-didodecylfluorene (PDADF) was synthesized through a Sonogashira coupling reaction. A solution-processed thin film transistor device showed a carrier mobility value of $6.0\;{\times}\;10^{-4}\;cm^2/Vs$ with a threshold voltage of -17 V and a capacitance ($C_i$) of $10\;nF/cm^2$.
