Selective Deposition of Conducting Polymers on Hydroxyl-Terminated Surfaces with Printed Monolayers of Alkylsiloxanes as Templates

6480 Introduction C onj ugated organic polymers are incre asingly imp ortant as active materials in optoelectronics,l microelectronics,2 micr oelectrom echanical systems (ME MS), 3 sensors, a and related areas.s Forexample, the undoped, semiconductive forms of conjugated polymers are used in the fabrication of microelectronic devices such as diodes, light-emitting diodes (LEDs), and transistors.l'2 The doped, conductive forms of conjugated polymers are being evaluated as potential alternatives to metals as connecting wires and conductive channels, since the conductivity of these materials can be tuned over a wide range by changing the dopant and./or doping level. Flexible, all-plastic, micro-electronic devices based on conjugated organic polymers are now appearing in prototype forms.6'7 Many of these applications require the formation of patterns and structures of conjugated organic polymers
