Photo-lithography of xanthate precursor poly(p-phenylenevinylene) polymers

Johnson, Ross S.; Dirk, Shawn M.

Conjugated polymers such as poly(p-phenylenevinylene) (PPV) have attracted a great deal of attention due to their optoelectronic properties. The ability to control the lateral spatial resolution of conjugated polymers will allow for improved integration into electronic devices. Here, we present a method for photo-patterning xanthate precursor polymers leading to micron scale spatial control of conjugated poly(p-phenylenevinylene). Our photolithographic process is simple and direct, and should be amenable to a range of other xanthate or dithiocarbamate precursor PPV polymers.
