Electrochemical Patterning of a Polyfluorene Precursor Polymer from a Microcontact Printed (μCP) Monolayer

Selective area electropolymerization of a precursor polymer in a microcontact printed pattern was used to generate a patterned conjugated and fluorescent polymer thin film. The precursor polyfluorene polymer, which has photoluminescent properties defined by the polymer main chain and electropolymerizability from the pendant carbazole units, was synthesized using a Yamamoto coupling route. The polymer was then electrochemically deposited and cross-linked selectively on the alkyl SAM defined regions to form patterns (
